%X 针对三相异步电动机标准滑模控制中的抖振问题，提出一种基于模糊逻辑滑模控制（FLC SMC）算法的异步电动机防抖振控制策略.基于系统状态变量非连续函数所创建的“滑动面”，引入模糊逻辑控制器来取代传统切换函数？？k？？？？1,2？？？？sgn？？〖JB((〗s？？？？1,2？？〖JB))〗？В？并利用SMC等效控制和FLC控制器的配合实现状态轨迹沿滑模面的平滑移动.本文推导给出SMC控制率和FLC控制器隶属度函数，并据此设计FLC SMC三相异步电动机仿真实验模型.通过仿真对比显示，所提算法对控制参数及负载转矩变化具有更好的鲁棒性，能有效起到防抖振效果.<br>In order to solve the problem of chattering in standard sliding mode control of three phase asynchronous motor, this paper proposed a fuzzy logic based sliding mode (FLC SMC) control strategy for induction motor in anti buffeting control.This control strategy created a “sliding surface” base on the system state variables of non continuous function, and introduced the fuzzy logic controller to replace the traditional switching function ？？k？？？？1,2？？？？sgn？？〖JB((〗s？？？？1,2？？〖JB))〗？？, and it used the combined SMC and FLC controller to realize the state smoothly mobiling trajectory along the sliding surface.This paper deduced the SMC control method and also presented the membership functions of FLC controller, according to which it designed the FLC SMC three phase asynchronous motor simulation model.Through the simulation comparison showed, the proposed algorithm has better robustness control for parameters and load torque change, which could effectively to prevent the chattering effect
