基于模糊自适应整定PI感应电动机直接转矩控制的研究

针对采用常规PID控制的感应电动机直接转矩控制的不足,为了进一步提高直接转矩控制系统的性能,设计了一种模糊自适应整定PI速度调节器,根据速度偏差与偏差的变化率来实时调整参数。在SIMULINK/PLECS环境下进行了仿真,并与常规的PI速度调节器进行了对比。仿真结果表明,采用模糊PI速度调节器可以提高系统的响应速度和抗干扰能力,验证了该控制方案的正确性和有效性。

The study of induction motor direct torque control based on fuzzy adaptive tuning PI

Aiming at inadequation of conventional PID control for induction motor direct torque control problem,in order to further improve the performance of direct torque control system,a fuzzy adaptive tuning PI speed regulator is designed,according to the speed deviation and the deviation of the rate of change to real-time adjustment of parameters.A simulation is carried out in SIMULINK/PLECS environment,and compared with the conventional PI speed controller.The simulation results show that the fuzzy PI speed regu...
