Closed loop control of solar powered boost converter with PID controller

Abstract

The power converter is a critical component of distributed generation system, particularly for renewable energy system based distributed generators. This paper presents a PV based boost converter with closed loop control by the use of PID controller. The PV module is modelled in MATLAB-Simulink Environment and is directly fed to the boost converter and the duty ratio control is obtained by means of PID controller. A state space average model of the boost converter has been developed and by Ziegler Nichol's method the parameters of PID Controller are obtained. All the simulation results are obtained using MATLAB.
