摘　　要：矩阵变换器的输出电压易受各种因素的影响,为了改善输出性能,将自抗扰控制技术应用于矩阵变换器的闭环控制中。分析了自抗扰控制器的特性,提出了一种双闭环自抗扰控制策略,即电流内环与电压外环均采用一阶简化的自抗扰控制算法。仿真结果表明:该方法不仅可以有效地抑制多种扰动的影响,而且比PI控制具有更优的动静态性能,可满足高性能矩阵变换器系统的控制要求。The output voltage of matrix converter（MC）is easily affected by various disturbance factors.In order to improve the performance of output,an auto disturbance rejection control（ADRC）technology is applied to the MC closed-loop control.The character of the ADRC is analyzed in detail and a novel strategy of inner 1st order ADRC and outer 1st ADRC is proposed.The simulation results show that the dual close-loop ADRC control strategy not only can effectively restrain the multidisturbance but also is superior to the tradition PI control in static and dynamic performance thus to meet the requirements for the high-performance MC control system.
