Hybrid parametric/non-parametric models for lifespan modeling of insulation materials

HAL (Le Centre pour la Communication Scientifique Directe) (2016)

Farah Salameh Antoine Picot Pascal Maussion Marie Chabert

This paper considers the problem of insulation material lifespan modelling. This problem is crucial for aircraft reliability since about 40% of electrical machine failures stem from insulation. According to the material physical properties and to the sightings reported in the literature, the proposed model should relate the logarithm of the insulation lifespan to the logarithm of the electrical stress factors (voltage and frequency) and to the temperature. The possible interactions between these three predominant aging factors must be also considered. Note that, due to a constraint of low experimental cost, the number and configuration of experiments were optimized through a design method. Parametric modelling through multilinear regression requires the estimation of a potentially high number of parameters in view of the reduced data set. The method proposed in this paper thus combines parametric and non-parametric approaches. First, a decision tree automatically classifies the experiments into ranges corresponding to relevant operating modes. Indeed, this method recursively partition the training set by selecting, at each node, the best separating variable and its best splitting value according to prediction performance. However, the predictive model produced by this tree is piecewise constant since a constant value is associated to each leaf of the tree. In this paper we combine this approach with parametric modelling, by associating a multilinear regression model to each region identified by the tree. This approach brings a better understanding of the aging phenomena through the hierarchical organization of the factors and also provides simple, specific and thus effective multilinear models in each lifespan range. The method performance is analysed through real data: training and test sets correspond to experiments on twisted pairs covered by an insulating varnish. The proposed method shows improved performance with respect to multilinear regression on one hand and to regression trees on the second hand.

Mechanical faults detection in induction machine using recursive PCA with weighted distance

2022 IEEE International Conference on Industrial Technology (ICIT) (2019)

Antoine Picot Jérémi Régnier Pascal Maussion

An original method for multi-fault detection in synchronous machine is proposed in this paper. This method aims to answer two questions: how to detect a fault when only the normal functioning is known? How to differentiate two different faults from one fault with two severities? The proposed method relies on the use of a recursive Principal Components Analysis (PCA), which is updated each time a new fault is detected. The detection is based on a weighted distance criteria that takes into account the contribution of the different components. A geometrical criteria is also proposed to differentiate new faults from existing ones. The method has been successfully tested on a simulation database of motor currents with different levels of unbalance and eccentricity. It is then tested on real data from a 5.5 kW synchronous machine with three different levels of unbalance.

Lifespan Modeling of Insulation Materials for Low Voltage Machines: films and twisted pairs

HAL (Le Centre pour la Communication Scientifique Directe) (2014)

Antoine Picot David Malec Marie Chabert Pascal Maussion

This paper deals with the modeling of insulation material lifespan in a partial discharge regime. Accelerated aging tests are carried out to determine the lifespan of polyesterimide insulation films under different various stress conditions. The insulation lifespan logarithm is modeled as a function of different factors: the electrical stress logarithms and of an exponential form of the temperature. The model parameters, or so-called factor effects, is estimated on a training set. The significance of the factors is evaluated through the analysis of variance (ANOVA). In a first step, the design of experiment method (DoE) is considered. The associated lifespan model is linear with respect to the factors. This method is well-known for reducing the number of experiments while providing a good accuracy. In a second step, the response surface method (RSm) is considered. This method takes also into account some second order terms and thus possible interactions between the stress factors. Performance of the two methods are analyzed and compared on a test set.

Evolution de la maquette de TP d'automatique pour la commande en position d'un papillon motorisé

J3eA (2009)

Didier Peytavi Pascal Maussion

Cet article présente une évolution de la maquette papillon d'admission d'air, utilisée comme support de formation à l'automatique. La réalisation d'une commande numérique implantée dans un microcontrôleur PIC et d'un amplificateur à découpage MLI, permet à la maquette de se rapprocher beaucoup de l'application industrielle réelle. Le boîtier de commande dédié à cette manipulation, permet sur cet actionneur embarqué, de tester différentes méthodes d'identification et de commande, principalement basées sur des démarches expérimentales de terrain, d'emploi simple et rapide. La manipulation est utilisée cette année dans la formation des élèves ingénieurs du département de Formation Génie Electrique-Automatique de l'ENSEEIHT (Ecole Supérieure d'Electrotechnique, d'Electronique, d'Informatique, d'Hydraulique et de Télécommunications de Toulouse).

Experimental fuzzy control improvement with surface response methodology for power electronics

Proceedings of the Annual Conference of the IEEE Industrial Electronics Society (2006)

J. Faucher Pascal Maussion

Surface response methodology is used in this paper to improve the dynamic performance of pre-established settings for PID-like fuzzy controller dedicated to under-damped behaviour systems with hard load variations. Only two open loop successive step input tests are required for controller parameter tuning with only one voltage sensor. Using information given by experimental designs, the experimental response surface is estimated. As a consequence, the analytical optimum could be found between the chosen levels of the experimental parameters. Dynamic performance on the output voltage are significantly improved but the robustness versus the reference level decreases

A New Shaping Method for Fuzzy State Feedback Tuning on a Power Converter

J. Faucher Pascal Maussion

Although linear state feedback control is classical, fuzzy state feedback is rather rare and there is no simple method for tuning. A new method for that controller tuning trough experimental designs with a reduced set of experiments is presented and applied to a dc/dc converter with an under damped behavior and hard load variations. The results will be compared either to PID control or to linear state feedback control

Acoustic Resonance Characteristics in a High Pressure Sodium Lamp

IEEE Industry Applications Society Annual Meeting (2008)

Labo Chhun Pascal Maussion Georges Zissis Sounil Bhosle David Buso

In the last decades, the high pressure sodium (HPS) lamp has been developed to be supplied in high frequency in order to increase the lighting efficiency of the system lamp/ballast. However, at some given frequencies, standing acoustic waves, namely acoustic resonance (AR), might develop in the burner and cause lamp luminous fluctuation, extinction and destruction in the most serious case. Two main characteristics of the acoustic resonances in a 150 W HPS lamp are presented in this paper to seek for a control method to avoid the lamp AR. The first one is the characteristic of the lamp AR threshold power, and the last one is the differences between forward and backward frequency scanning effects. Both characteristics allow us to further understand the AR and to better control the lamp.

Improvements on experimental modeling of the losses in induction machine with Taguchi orthogonal plan

Phok Chrin B. Dagues Michaël David Pascal Maussion L. Bun

Maximum efficiency of induction generators is a significant issue of renewable energy applications since resource is limited and sometimes because of expensive technology. This paper presents a modeling method of iron, copper and mechanical losses in an induction machine based on the design of experiments and Taguchi orthogonal plans. The model involves several parameters such as rotor speed (slip), switching frequency, supply voltage, supply frequency and the modulation index of the inverter. Temperature remains under control in order to get rid of resistance variations. The resulting loss model will be the starting point of a future online efficiency optimization, as the operating point of the induction generator will be set as thanks MPPT systems (Maximum Power Point Tracking). In many cases and particularly in developing countries, no information is provided on the electrical machines. Consequently, a simple method is required for on-site parameter identification especially if the computing resources are limited. Taguchi method is simple, well-known for reducing number of experiments and for improving model accuracy.

Optimized fuzzy logic controller parameters for open-loop stable or evolutive electromechanical systems

Pascal Maussion Daniel Hissel

This paper describes a new and original tuning method of a fuzzy PID-like controller which is just a particular case of nonlinear controllers. As Ziegler-Nichols or Broida methods for the tuning of conventional controllers, this method is based on only one experiment: the open-loop step response of the process (which is supposed to be open-loop stable or evolutive). In this way, this method can be seen as a very simple on-site industrial tuning methodology. In this paper, we provide pre-established settings for the fuzzy logic controller parameters in terms of parameters that have been identified from the open-loop experiment. These settings have been obtained using the experimental designs methodology and a simplex algorithm. They are optimized considering an IAE-criterion on a very common industrial benchmark. The pre-established parameters are then validated on two experimental systems: a DC/DC buck converter and a permanent magnet synchronous machine.
