Abstract :
State-space averaging method is a powerful way to treat analysis and control problems for variable structure systems. The transfer function model of the buck converter is proposed by using the State-space averaging method. A compensator device of the system is designed by using the knowledge of the series compensation. And the stability of the closed-loop Buck system has greatly improved. At last the simulation model of closed-loop system is founded by using the MATLAB. The conclusion can be reached that the dynamic performance indices of the after-compensation system have greatly improved. All this system can satisfy the demand of the design.
