This paper proposes a new passivity-based control method for APF. Such method introduces damping matrix R a to improve harmonic compensation effect and accelerate the convergence speed. It also includes Robust stability analysis and the results proved that APF system can still maintain stable after the parameter variation and load disturbance. Based on the Robust analysis, the control equations are further simplified to make them more realizable. This new passive current control strategy is supported by simulation results.
