| 摘要: |
| 针对一种适用于现有中高压配电系统的三相并联混合型有源电力滤波器，首先基于PWM原理建立了其状态空间模型，在此基础上设计出一种基于线性自抗扰控制技术的电流跟踪控制器。该控制器能够估计出系统所有不确定因素和外部干扰等引起的总扰动并进行补偿，实现指令电流的实时跟踪，其算法简单，易于实现，具有一定的工程应用价值。数字仿真和物理实验结果验证了等效模型的正确性和所设计的电流跟踪控制器的控制品质优于PI控制器。 |

| Abstract: |
| A state-space model is established based on PWM（Pulse Width Modulation） theory for the three-phase SHAPF（Shunt Hybrid Active Power Filter） used in middle- and high-voltage distribution systems and a current tracking controller based on LADRC（Linear Auto Disturbance Rejection Control technique） is designed for it，which estimates and compensates the general disturbance caused by all unknown internal dynamics and external disturbances to achieve the real-time tracking of command current. Its control algorithm is simple and easy to implement in practical projects. Simulative and experimental results validate the correctness of the established model and the control performance of the designed controller superior to PI controller. |
