Simulation and Analysis of Flyback Ccm Inverter with Ic Technique Forpv System based Discrete-Time Repetitive Control

Abstract

In this project we are implementing the discrete-time repetitive controller (RC) during the continuous conduction mode of operation is applied for the PV source. In this paper we use the IC technique; it is used to track the maximum power point of the PV source. MPPT can minimize the system cost and maximize the array efficiency. The proposed system is simple and cost effective. According to the comparison to the conventional controller and the repetitive controller it is obtain as a good tracking ability and disturbance rejection which is applied to fly back inverter during CCM operation. The IC algorithm was designed to control the duty cycle of Buck Boost converter and to ensure the MPPT work at its maximum efficiency. Therefore, according to the Conventional controller results which is shown that it is poor control performance because of it effect of the right-half-plane zero during the CCM operation. Which also allow the tracking and rejection of periodic signals within a specified frequency range the RC scheme by utilizing the low-pass filter. Here the stability of the closed loop system has been derived and zero tracking error will be achieved along with the stability of the closed loop system. By using the simulation results we can analyze the proposed method.
