摘要

The average model of the forward converter is build with the state-space average method. The open-loop transfer function model is deduced in detail according to the average model of the forward converter, the controller is designed based frequency domain by the type Ⅲ compensation network. And the stability of the control system has been improved. The modeling and simulation of system was implemented based Matlab. The results of simulation confirm that the controller is capable of reduced steady state error and improve controller's reliability during power supply disturbance and load disturbance.
