由于传统PID控制器存在着参数整定复杂的缺陷,应用在直接转矩控制( DTC)的调速系统中时,调速的范围和精确度都受到很大限制。该文研究了一种新的异步电机直接转矩调速系统,即在自抗扰控制器(ADRC)中运用交叉熵算法(CE)对速度参数进行优化。仿真实验表明:基于CE-ADRC异步电机直接转矩控制系统,在调速范围和精度方面比经典PID控制器更具优越性。

Classic PID controller can ’ t fulfill the requirements of a wide range and high precision speed modulation of induction motor based on direct torque control ( DTC ) owning to its own defects of complex parameters tuning. A new direct torque control speed modulation of induction motor based on ac-tive disturbance rejection control( ADRC) with cross entropy algorithm ( CE) for tuning speed controller parameters was constituted. The simulation results show that the direct torque control speed modulation of induction motor based on CE - ADRC asynchronous motor has more advantages in the speed range and accuracy than the classical PID controller.
