Implementation of new control method based on dynamic evolution control for dc-dc power converter

Abstract

This paper proposes a new control technique for dc-dc power converter. Design and implementation of the proposed control method for dc-dc power converter is provided. A new approach for converter controllers synthesis based on dynamic evolution control theory is presented. In order to synthesize the converter controllers, this method uses a simple analysis of non linear equation models of the converter. The synthesis process is simple and requires a quite low bandwidth for the controller. Therefore, this control method is suitable for digital control implementation. In this paper, synthesis example of boost dc-dc converter is discussed in detail. DSP based Controller algorithms for these converters are implemented. Performance of the proposed dynamic evolution control under step load variation condition is tested through simulationandexperimental.Simulation and experiment results show that the proposed techniques are suitable for controlling dc-dc power converter.
