Abstract: Deadbeat current tracking control technique can be adopted to improve the compensation effect of shunt active power filter based on three-phase three-wire system.The formula of deadbeat control algorithm is derived;predictive instruction current is obtained by constructing harmonic current repetitive predictor;and active power filter system in the platform of Matlab/Simulink is modeled and simulated.The simulation result indicates that compensation current is identical to instruction current in both amplitude and phase,and the purpose of deadbeat control is achieved.Moreover,harmonic current is weakened effectively.
