在分析感应电机效率优化控制策略的基础上,提出了一种兼顾感应电机动、稳态效率和转矩快速响应的控制策略.首先,设计了一种适用于感应电机效率优化控制的基于自抗扰控制器(ADRC)的解耦控制方案,为了提高轻载时效率优化运行时的转矩动态响应的快速性,设计了一种去掉跟踪微分器(TD),并且采用线性函数的ADRC.然后,为获得ADRC最佳参数,引入了具有全局快速搜索能力的变尺度混沌优化参数的方案.仿真结果表明,与PI控制器相比,该控制方案不仅能提高轻载时电动机的动、稳态运行效率,而且具有良好的转矩响应效果,并且对外部扰动具有较好的鲁棒性和适应能力.

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.
