【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ip-iq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]:Aiming at the current tracking of active power filter (APF), a state feedback control strategy is proposed, which is applied to the three-phase parallel hybrid APF system to replace the popular PID control and overcome the overshoot of PID control. Compensate for the shortcomings of large errors. According to the topology of the hybrid active power filter, the mathematical model is established and the feedback control law is deduced. At the same time, the harmonic current is detected by ip-iq algorithm, and the DC side capacitor voltage stability is controlled by PI. The HAPF system is simulated with Matlab/Simulink software and compared with the traditional PI hysteresis control method. The results show that the algorithm can obviously improve the tracking performance of the system and improve the harmonic compensation effect of the active filter.
