Implementation of PI Controller for Boost Converter in PV System

This paper describes the implementation of
Proportional Integral controller for boost converter in Photo
Voltaic system. The reason behind using PI controller is it
removes the delay and provides fast control. There are many
types of controller that can be used to implement the elegant and
effective output. The PI stands for Proportional and Integral
Controllers, which are designed to eliminate the need for
continuous operator attention, thus provide automatic control to
the system. In this paper the PI controller is used and the Kp and
Ki gain value is calculated by using trial and error method. This
paper is focusing on implementing PI controller to boost
converter. The boost converter is mainly used for voltage step up
operation. So, the output voltage is greater than the input
voltage. The PWM signal generator is used for commutation
purpose in boost converter. The boost converter model is
simulated by using MATLAB/SIMULINK. The boost converter
maintained the constant output voltage in the load.
