Abstract

Quadratic stability is an important performance for control systems. In this paper, the model of Buck Converter in DCM is built based on the theories of hybrid systems (HS) and switched linear systems (SLS) primarily. Then quadratic stability of SLS and two switching rules based on state feedback and hybrid feedback are introduced. The problem of Buck Converter’s quadratic stability is researched afterwards. In the end, the simulation analysis and verification are provided. Both experimental verification and theoretical analysis results indicate that the output of Buck Converter in DCM has an excellent performance via quadratic stability control and switching rules. This analysis method can be also used directly to study the quadratic stability of other switched converters.
