摘　　要：在机电传动实验系统中,矢量控制是重要的实验内容之一,但电机参数时变和负载波动等因素对系统性能有很大的不良影响,针对这一问题,本文采用了一种自适应模糊PID控制器作为机电传动实验系统中矢量控制的速度调节器,该调节器可以利用模糊控制规则根据不同偏差E和偏差变化率Ec对PID参数的要求,在线对PID参数进行调整。实验和仿真结果表明,采用该控制器的实验系统不仅具有良好的动静态性能,而且有较好的鲁棒性和抗干扰性能。In the motor experiments, vector-controlled induction motor drive is one of the most important experiments. An adaptive fuzzy PID controller is designed to improve the performance of vector-controlled systems during parameter variations and load disturbance. It is used as the speed controller of slip frequency vector-controlled induction motor drive. The controller adjusts PID parameters by fuzzy rule to meet the challenge of variable E and Ec. Experiment and simulation results show that the controller enhances the system steady-state precision and dynamic performance and it is very robust.
