摘要/Abstract

摘要： 针对有源电力滤波器的电流跟踪,提出了采用状态反馈控制策略,应用于三相并联型混合有源电力滤波器系统,取代目前流行的PID控制,克服PID控制存在的超调大、补偿误差大的缺点。根据所选用混合有源电力滤波器的拓扑结构,建立了其数学模型,推导了反馈控制律,同时谐波电流检测采用i_p-i_q检测算法,直流侧电容电压稳定采用PI控制。采用Matlab/Simulink软件对HAPF系统进行仿真,并与传统的PI滞环比较控制方法进行对比,结果表明,该算法能够明显地改善系统的跟踪性能,提高有源滤波器的谐波补偿效果。

Abstract: According to the current tracking of active power filter, a state feedback control strategy was applied to three-phase shunt hybrid active power filter system, replacing popular PID controller, to overcome the drawbacks of the PID controller, such as big overshoot, error compensation etc.. The mathematical model was established and the feedback control law was derived based on the topological structure of hybrid active power filter selected. Moreover, the current detection used i_p-i_q detection algorithm while the stability of capacitor voltage in DC side used PI control. MATLAB/Simulink was applied to simulate the HAPF system, comparing with the traditional PI hysteresis comparison control method. The results show that the state feedback control algorithm can obviously improve tracking performance of the system, and improve the harmonic compensation effect of APF.

Key words: active power filter, state feedback, current tracking control, harmonic compensation
