Improving the Performance of Current Controller in a Grid Connected Renewable PV System using Fractional Order Controller

摘要

This paper focuses on the implementation of fractional order control techniques in real world control system for improving the performance of current controller used in grid connected PV system. Two types of controller are usually used in the grid connected system they are Linear and non-linear controller. PI-controller being a linear controller is basically used in the grid connected PV system. Therefore Fractional order controller with Linear PI controller is used in this paper to enhance the performance of current controller. MATLAB Simulink software is used to implement and test the controller. Fractional order operator function and codes are used to optimise and tuning of the controller.
