摘　　要：利用Simulink软件建立了模型参考自适应无速度传感器矢量控制系统仿真,分析了比例积分转速调节器的缺点,提出在转速调节器中的积分器采用一种模糊控制算法,此算法根据转速偏差和偏差变化来修改积分器的输入,使积分器提前退饱和。仿真结果表明,在转速调节器中采用模糊控制算法使调节器提前退饱和,减小了调速系统超调量和调节时间,提高了系统抗干扰性。The simulation for the senseless vector controlling of the induction motor based on the MRAS is established by the software Simulink, the disadvantages of PI speed The simulation result shows that by use of fuzzy controlling algorithm in speed regulator, the regulator can be de-saturated in advance, the regulator and adjustment time of speedadjusting system can be reduced, and the anti-interference of the system can be improved.
