| 摘 要： | 提出了一种模糊控制和低通滤波器补偿相结合的控制方法。这种方法采用低通滤波器代替积分环节的基础上，根据定子磁链的实际值与给定值之间的关系，推导出磁链的补偿公式，然后通过模糊控制进行开关状态选择，从而控制逆变器的输出。仿真和实验结果表明，该方法能够提高磁链的观测精度，增强系统的鲁棒性，并能使直接转矩控制系统的低速性能得到较大的提高。

| Abstract: | A novel method which combines fuzzy control with low-pass filter compensation was proposed.According to relationship between real and estimated values of the stator flux linkage,the compensatory formulas of the estimated flux linkage and its principle block diagram were presented.By fuzzy controller select the switch station.Use this method control converter's output.The simulation and experiment results showed that this method gives satisfied estimation of stator flux and improve direct torque control system good robust.The performance of low-speed have been improved in direct torque control system, confirming the validity of the method. |
