Abstract: A soft-start system of asynchronous motor is a typical nonlinear,time-varying and class of high order system.The adaptive fuzzy controller based on variable universe is applied to an asynchronous motor.The simulation model based on Matlab/Simulink of soft-start is established,and the simulation result of adaptive fuzzy controller based on variable universe is provided and it compares to the methods of traditional PID control and conventional fuzzy logic control.The simulation result shows that application of this method to soft-start is valid.It brings advantages such as no need for exact models,fast response,and high precision and strong robustness,and it is superior to other ones.

Key words: asynchronous motor, variable universe, adaptive fuzzy control, soft-start, simulation

摘要: 异步电机软启动系统是一个时变、非线性的高阶系统,将变论域模糊自适应控制方法应用于异步电机的软启动控制系统中,并建立电机软启动控制系统的Matlab/Simulink的仿真模型,给出了变论域自适应模糊控制方法的仿真结果,与传统PID控制和常规模糊软启动控制方法进行了比较。仿真结果表明,该方法具有无需精确建模、响应快速、精度高、鲁棒性好、适应性强等优点,切实可行,并优于其他控制方法。
