摘　　要：双级矩阵变换器由于减少了直流储能环节,输入输出两级之间存在严重的耦合现象,变换器的输出性能容易受到外界干扰的影响.为了提升双级矩阵变换器的抗扰性能,引入了自抗扰控制技术,针对双级矩阵变换器系统提出了一种在非线性状态误差反馈律部分增加类积分环节的改进型二阶自抗扰控制策略.仿真结果表明:与传统控制策略相比,采用改进型二阶自抗扰控制策略抑制负载突变扰动的效果更好,进一步提升了变换器的动态响应速度和抗扰性能.Since the two-stage matrix converter reduces the DC energy storage link,there is a serious cou-pling phenomenon between the input and output stages,and the output performance of the converter is easily affected by external interference.In order to improve the anti-disturbance performance of the two-stage ma-trix converter,this paper introduces the auto-disturbance rejection control technology.Aiming at the two stage matrix converter system,an improved second-order active disturbance rejection control strategy is pro-posed,which adds an integral part of the nonlinear state error feedback law.The simulation results show that compared with the traditional control strategy,the improved second-order active disturbance rejection control strategy has a better effect on suppressing the load sudden disturbance,and further improves the dynamic re-sponse speed and anti-disturbance performance of the converter.
