摘要

An algorithm has been designed by combining fuzzy reaching law with VSC after the PWM module has been analyzed in depth. It is verified that this algorithm is feasible through simulation. After considering these three algorithms, it is proved that the new algorithm can improve the system performance of dynamic and static property. This algorithm can both reduce control period and prevent system buffeting which greatly increases the stability of the system. Moreover, it can run under unit power factor and has certain self-adapting ability and anti-jamming. It has some practical value.
