Hybrid Active Power Filter DC Bus Control Based on Fuzzy PID Control

With the existing problem of the static error and the overshoot of DC bus voltage control methods, a hybrid active power filter control system was designed. Considering special characteristics of the DC bus voltage control, the parameter self-tuning fuzzy PID control method combine the fuzzy control with PID control is proposed. Compared with traditional PID control method, this control method has the feature of robust, the small overshoot and the steady-state error. Simulation results prove that the control system possesses the excellent Correctness and Feasibility.
