| 摘 要： | 鉴于并联混合型有源电力滤波器(SHAPF)的动态性能要求,针对一种适用于现有中高压配电系统的三相SHAPF,在其状态空间模型的基础上,设计出一种基于线性自抗扰控制(LADRC)技术的双闭环控制系统。基于LADRC的控制系统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,补偿性能良好,其算法简单,易于实现,具有一定的工程应用价值。仿真结果验证了基于LADRC的控制策略的有效性。

| Abstract: | The high performance control of three-phase shunt hybrid active power filter(SHAPF) with hybrid dynamic,which fits for existing high-voltage power distribution systems is considered.A double closed-loop controller based on linear auto disturbance rejection control technique(LADRC) is designed after the state-space model.And the controller is able to estimate and compensate the general disturbance that includes all the unknown internal dynamics and exter-nal disturbances to achieve compensation with superior control quality.The proposed control algorithm is simple and easy to implement and can be easily adopted in practice.Simulation results indicate the validity of the LADRC. |
