Abstract

ABSTRACTIn this paper, the design and analysis of Fractional Order PID (FOPID) controller for the application of the solar photovoltaic system is proposed. At the outset, a solar PV system is considered to investigate the better performance of the FOPID controller compared to PID controller. Fractional order PID (FOPID) controller is used to improve the dynamic response of the system and the optimal gain values are tuned by using FOTF toolbox. A Fractional order controller that has been conceptualized to improve the system performance, particularly to improve the rejection of possible disturbances, which may occur in the input voltage. The performance analysis and comparison of PID controller and FOPID controller is done using MATLAB. The working method of the proposed technique is demonstrated with the help of Boost converter. It is designed in order to tap the solar energy and convert it into an electrical energy.
