摘　　要：本文针对可再生光伏储能电气系统的异步电机控制问题进行了探讨,并且针对光伏阵列系统存在的能源供应的不连续和不规律问题,在供电系统中添加了蓄电池进行联合供电。这种控制系统存在高度的非线性特征,为此引入滑模控制算法进行控制,这种控制技术在控制参数趋近滑模面时,存在抖振现象,为解决该问题,控制信号的切换函数利用具有一定宽度的滑模面对传统的滑模面进行替代,同时对于符号函数,在开关表面周围引入一个边界层,可实现符号函数离散继电器动作的连续逼近。最后,该方案通过搭建的硬件实验平台进行了仿真验证。In this paper,renewable photovoltaic energy storage motor control problems of electrical system were discussed,and in view of the existing photovoltaic array system of energy supply is discontinuous and irregular problems in the power supply system with battery power. There are highly nonlinear characteristics of the control system,this paper introduced control sliding mode control algorithm,the control technology in the control parameters of reaching sliding surface,the chattering phenomenon,in order to solve the problem,instead of switching function control signal using the sliding surface with a certain width of the traditional sliding surface,at the same time for the introduction of symbolic function. A switch in the boundary layer around the surface,can realize the continuous approximation function of discrete symbol relay. Finally,the scheme was verified by simulation experiment platform.
