摘　　要：针对VIENNA整流器采用传统比例积分控制存在动态响应慢、抗干扰能力差等问题,提出自抗扰和滑模控制相结合的复合控制,将滑模控制中的滑模面和切换律引入自抗扰控制器中,设计了基于改进的自抗扰控制的VIENNA整流器电压外环控制器,采用切换律的概念,以获取整流器系统的主输出,增强了VIENNA整流器的抗干扰性并提高了系统的稳定性。仿真和样机验证了该控制策略的可行性。For the VIENNA rectifier,the traditional proportional integral control has the problems of slow dynamic response and poor anti-interference ability.A compound control combining anti-interference and sliding mode control is proposed to introduce the sliding mode surface and the switching law in sliding mode control into the anti-interference.In the controller,the VIENNA rectifier voltage outer loop controller based on improved auto disturbance rejection control is designed.The concept of switching law is adopted to obtain the main output of the rectifier system which enhances the anti-interference of VIENNA rectifier and improves the stability of the system.Simulation and prototyping verify the feasibility of this control strategy.
