In photovoltaic (PV) grid-connected system and active power filter (APF), there is same topology of power electronic devices. In this paper, first, a PV grid- connected system with APF function is designed. Then, to rely on jointly a proportional- integral-derivative (PID) controller and a neuro-fuzzy controller, compound control law is designed for inverter current control system, which is working in PID controller and a neuro-fuzzy controller parallelly. The PID controller is used to guarantee the global asymptotic stability of inverter current control system in a compact space. The neuro-fuzzy controller is used to get a good dynamic performance. Finally, a good result with simulations is got through choosing and changing the parameters and the feasibility, adaptability and robustness of the control are testified by this result.
