| 摘 要： | 针对同步电机磁场定向控制系统受负载扰动、电机参数变化影响问题,将自抗扰控制器(ADRC)应用于调速系统中.为解决传统磁链观测器存在的直流偏置和依赖电机参数的问题,提出了基于ADRC的磁链观测器.仿真结果表明:ADRC对负载扰动和参数变化具有较强的鲁棒性,并且响应速度快、超调小,具有优良的稳态和动态性能;改进后的磁链观测器能有效抑制直流偏置和参数变化带来的影响,提高磁链的观测精度.

| Abstract: | In order to deal with the negative effects of load disturbances and parametric perturbation on the field oriented control system of synchronous motors, an active disturbance rejection controller (ADRC) was transplanted into the speed control of synchronous motors. A novel flux observer based on ADRC was proposed to solve the problems such as the direct current bias and parametric perturbation of conventional flux observers. Simulation results show that the ADRC ensures very good robustness to load disturbances and parameter variation with fast response, small overshoot, and good static and dynamic performances. The improved flux observer not only restrains effectively the direct current bias and parametric perturbation, but enhances the precision of the flux. |
