Performance recovery of uncertain nonaffine systems by active disturbance rejection control

Measurement and Control (2023)

Lilong Tan Zhixiang Chen Qinhe Gao Jifang Liu

This paper studies performance recovery problem of a class of uncertain nonaffine strict-feedback systems with mismatched uncertainties. First, the strict-feedback nonaffine system with mismatched system dynamics is transformed into an integrator-chain nonaffine system by a diffeomorphism. Second, the transformed system is converted to an affine one by constructing an auxiliary control input term, and dynamical uncertainties and external disturbances are viewed as total disturbance of the affine system. Then, a two-time-scale active disturbance rejection controller (ADRC) is designed for the transformed affine system. Under some mild assumptions, it can be proved that the proposed ADRC-based closed-loop system can achieve performance recovery and weak performance recovery in different cases of mismatched system dynamics, respectively. Experimental results on a magnetic levitation ball system demonstrate the effectiveness of the proposed control scheme.

Thoughts on Promoting Effective Docking and Maintaining Reasonable Price Fluctuation in Agricultural Products Production and Marketing

IOP Conference Series Earth and Environmental Science (2019)

Fantao Kong Haipeng Yu Jing Zhang Hongyu Zhang Jifang Liu

Abstract Ensuring the balance between supply and demand of agricultural products and keeping the basic price of agricultural products are the preconditions of reducing market fluctuation. According to the situation of production and supply of agricultural products and price fluctuation of agricultural products market in Inner Mongolia and Xing’an League, this paper condenses the primal problems existing in the agricultural products market in Inner Mongolia, studies the causes of these problems, makes overall plans for the structural reform of the supply side of agricultural products at present and in the future, in an effort to put forward reasonable countermeasures and suggestions for realizing effective docking of production and marketing of agricultural products and reasonable price fluctuation

Design and Implementation of Multi-factor Aided Spatial Interpolation Software Tool for Forest Biomass

Wei Sun Shanshan Cao Fantao Kong Jifang Liu

Forest biomass could quantify the complex relationship between the change of forest carbon storage and the carbon cycle in the environment. The accurate estimation results of forest biomass are the basis for the analysis and evaluation of forest ecosystem structure, function, quality and benefit. The distribution of forest biomass is the result of the interaction of structural factors and random factors. A typical data flow processing framework had been adopted, and a new ecological tool: Multi-factor assisted forest biomass spatial interpolation software tool (MFA-SIS) had been designed and implemented. The MFA-SIS had implemented complex algorithm logic in the underlying code, and simplified the pre-processing process of multi-factor assisted modeling data and forest biomass sample data. And the visualization interface could provide a good software module for forest biomass estimation that is easy to learn, practical and has great application potential, and provide a good underlying model algorithm tool support for the "double carbon" strategy proposed by China.

Development of vericiguat: The first soluble guanylate cyclase (sGC) stimulator launched for heart failure with reduced ejection fraction (HFrEF)

Biomedicine & Pharmacotherapy (2022)

Juan Xia Hui Nan Lei Tian Chengyuan Liang Jie Zhang

In recent years, with improvements in treatments for heart failure (HF), the survival period of patients has been extended. However, the emergence of some patients with repeated hospitalizations due to their worsening conditions and low survival rates followed. Currently, few drugs are available for such patients. Vericiguat was first drug approved for the treatment of symptomatic patients with chronic HF with reduced ejection fraction (HFrEF) to reduce the occurrence of worsening HF. This article provides comprehensive information about vericiguat in terms of drug design and development, structure-activity relationship (SAR), synthesis, pharmacological efficacy, and clinical practice. In addition, insights into the current vericiguat trials and treatments of HF are also discussed.

Effect of Kang'aiInjection on Th1/Th2 cytokines in human colon carcinoma cell line Lovo

Jifang Liu Yanchao Qi Min-ying Lu

：Objective To explore theeffect of Kang'ai injection on Th1/Th2 cytokine in human colon carcinoma cell lineLovo.Methods Lovo cells were cultured by conventional ways until they were in exponentialgrowth phase and then divided into 4 groups:one control group and three experimentalgroups with different concentration of Kang'ai injection.After 72 hours culture,Th1 typecytokines (IL-2,IFN-γ) and Th2.type cytokines (IL-4,IL-10) in the culturesupernatant of Lovo cells in each group were separately detected by double-antibodysandwich enzyme-linked immunosorhent assay (ELISA).Results After the coculture of Lovocells and Kang'ai injection,Th2 type cytokine levels in the supernatants were significantlower than the control group (P＜0.05),and Th1 type cytokines in each group were of littlechange.Conclusions Kang'ai injection markedly downregulated Th2 type cytokines in Lovocells,and contributed to the switching from Th2 to Th1. Key words: Kang'ai injection ; Th1/Th2; Reversion ; Immunotherapy

Several Relations Needed to Be Clarified in Designing the Professional Cultivation Plan for Vocational Colleges

Journal of Zhangzhou Institute of Technology (2010)

Jifang Liu

The process of cultivating professional students in a vocational college is one to make sure its objectives and specifications,to construct its mode through combination of working and learning,and thus to put into practice its plan.Before designing a scientific and effective professional students cultivation plan it is needed to make clear such relations as:relations between its mode and objectives,those between its plan and mode,those between its curriculum setting and objectives,those between teaching troupe constructing and curriculum setting,and those between training-and-internship condition constructing and curriculum setting.

Facility tomato picking system based on shelf life prediction and fruit maturity discrimination

2022 IEEE Asia-Pacific Conference on Image Processing, Electronics and Computers (IPEC) (2022)

Long Luo Wei Sun Shanshan Cao Jifang Liu Fantao Kong

In order to ensure the best taste and maturity of the picked tomatoes during the market, this paper designed a facility tomato picking system based on shelf life prediction and fruit maturity discrimination. Use the deep learning method to predict the shelf life of tomatoes and distinguish the ripeness of tomato fruits, and calculate the best picking time of tomatoes through the shelf life and fruit ripeness. The use of this system avoids the uncertainty of empirical judgment of picking time, improves economic benefits, and is of great significance to the development of intelligent fruit and vegetable picking.
