| 摘 要： | 定子电阻的变化将直接影响永磁同步电动机直接转矩控制系统的运行性能,而传统的滞环控制器不可避免地会产生较大的转矩和磁链脉动。为解决这一问题,可以在永磁同步电动机直接转矩控制系统中利用定子电阻观测器对定子电阻进行补偿,并且用模糊控制器代替传统的滞环控制器。仿真实验结果表明,利用该方法建立的基于定子电阻观测器的永磁同步电动机模糊直接转矩控制系统不但具有较小的转矩、磁链脉动,而且在电机参数发生变化或受到外部扰动的情况下,系统仍然具有快速响应性能。

| Abstract: | The stator resistance variation can affect the performance of direct torque control system of permanent magnet synchronous motor.Furthermore,conventional hysteresis controller inevitably produces high torque and big flux ripples.In order to solve this problem,resistance compensation is realized using stator resistance estimator in DTC system,and the conventional hysteresis controller is replaced by fuzzy controller.Simulation results are presented to illustrate that the dirve system has low torque and small flux ripples.Its quick responding performance is also proved even under the occurrence of parameter variation and external disturbance. |
