Abstract

This paper analysis about a design of a robust control conventional boost converter using linear matrix inequalities (LMI). LMI is the control technique where we can solve a problem exactly by efficient optimization algorithm LMI (solvers). The small signal model is used to analyze the conventional boost converter The proposed LMI methods guarantee a robust design with uncertainties and non linearity’s. Here we use standard optimization algorithm is used for a multi objective robust controller which is computed automatically. The proposed method gives an efficient boost converter in which poles placed are implemented by the operational amplifiers. Here PSIM simulations are used to validate the desired output waveforms.
Keywords: Boost Converter, LMI Technique, Pole Placement, State Space Analysis
