Abstract

This paper presents a discrete time generic model for variable structure system. The model is applied to any cyclic operating variable structure system such as power converters. The paper assumes switching frequency is an integer multiple of sampling frequency and the system uses the zero order hold. The circuit or system operates in cyclic mode with configurations possible series, the generated model is use to small signal and low frequency, the model validation is realized using Matlab/Simulink 2007.

Keywords
