[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.
