摘要：

The controller of active power filter has the demand for real-time, dynamic performance and control accuracy, based on the balance of power between input and output, the mathematical model of active power filter was established, and the novel nonlinear control method was proposed. Combining the nonlinear feedback control with adaptive control, adaptive control rate of the parameter was designed, the power instantaneous active reference current and the system's state equations which can ensure the stabilization of DC side capacitor voltage and track the harmonic currents accurately with unknown change in the parameters of lines and loads were obtained. Simulation and experimental results confirmed show that this control method is correct and feasible, and it has a better dynamic performance and stronger robustness.
