Active Disturbance Rejection Control and Chaos Optimization for Induction Motors Taking Dynamic Efficiency Optimization into Account
摘要
Abstract
A novel torque control strategy was presented for the optimization of efficiency in steady and dy-namic state as well as rapid torque response performance on the basis of analyzing the efficiency optimization control strategies for induction motors. Firstly, a new decoupling control scheme to the efficiency optimization for induction motors was proposed based on active disturbance rejection controller(ADRC). In order to pro-duce the fast transient response of torque, the proposed ADRC consists of linear functions without tracking differentiator(TD). With the high efficiency of global searching, the mutative scale chaos optimization method was introduced to optimize the parameters of ADRC. The simulation results show that the proposed ADRC can not only improve the efficiency of induction motor both in steady and transient states at low loads, but also provide good torque response performance than the conventional PI controller. It ensures good robustness and adaptability under external disturbance.关键词
