The linear motor is available for linear transition motion, because of its advantages, the motor design and its application have gradually increased, but the quantitative measurement system of thrust force has not been generalized. Need analysis of correct thrust for control performance improvement of HB-LPM (HB-type linear pulse motor). It is difficult to analyze HB-LPMpsilas thrust. In this paper, HB-LPMpsilas thrust is expressed to mathematical expression. And it is proved validity of this numerical formula by thrust measurement system. Two phase driver is composed. It is verified validity of numerical formula that measure waveform of electric current and voltage that is supplied in each phase.
In this paper, the empirical study for a hybrid generation system based on wind power which is leading renewable energy was performed. The simulation for the overall operation of the wind generator, diesel generators, monitoring system and a central controller operated in Demonstration Complex was carried out. In addition, the adequacy of the control algorithm was examined through the experiments.
The use of micro processor having μ-com functions has gradually increased. This paper describes the digital servo controller for linear pulse motor. The TMS320LF2407, made by TI(Texas Instruments Co.), is used as a arithmetic unit in control circuit, designed for motor drive and available for the implement of high performance
and miniaturization. Also, it can allow the sufficient debugging and downloading into control board for independent operation. A current control in order to carry out a position control is of a digital current control mode, and its implement confirmed the servo control performance of position control.
Equalizing the slate of charge of cell that affects the charge/discharge quality and efficiency of the battery through the charge/discharge characteristic experiments of batteiy source, we develope the high efficiency charge/discharge system which would be used in serial HEV with the constant engine-generator output For this, establishes the electrical model of Ni-MH battery appropriate to the high efficiency charge/discharge conditions. There is no model of Ni-MH cell, so we used Ni-Cd model and obtain the Ni-MH model through the experiment A reason that each cell has the same charge/discharge property for applying the cell model to serial/parallel connected battery source extensively is needed Therefore, in this paper, propose the Ni-MH charger/discharger has the equalization charging function and selectable cut-off function.
This paper presents a Switched Reluctance Motor (SRM) drive using the self-tuning control method to achieve the maximum torque. SRM has the difficulty to research it by an analytic method and to control the speed and torque because of the high non-linearity. So, in this paper, the self-tuning control method is proposed to relevantly control the turn-on/off angle in order to operate the SRM at the maximum torque. The feedback signals to control the turnon/ off angles are counted from the encoder pulse and the increment of phase current. At first, an adequate turn-off angle is searched by itself and then a turn-on angle is done. As the relationship between turn-on and turn-off angle is mutual dependent, the turn-on/off angle is controlled by a real time self-tuning control method in order to maintain the maximum torque. The proposed self-tuning algorism is verified by experiments.
