Hybrid Automata Modeling and Simulation for Single-Phase Shunt APF

摘要

Active power filter (APF) is a typical hybrid dynamic system. And the accuracy of its model directly affects the understanding of the movement laws and the design performance of the controller. According to hybrid automata modeling theory, partition of the state space in single-phase shunt APF movement is analyzed in this paper. Then the hybrid automaton model is established. The model can accurately reflect dynamical motion characteristics of the single-phase shunt APF. Simulation results illustrate the effectiveness and validity of the proposed mode.
