New approach of intelligent technique to Optimize Maximum power point tracking with PID controller by using the algorithm of fuzzy inference system

摘要

in this paper, new approach for maximum power point tracking MPPT with Proportional-Integral-Derivate PID controller is proposed to optimize the system. However, the main problem of classical MPPT is that the MPPT needs always to adjust voltage and current to obtained maximum output power which causes high steady state error and low response with oscillation fro photovoltaic system. Therefore, to improve the system performance, PID controller with fuzzy inference system FIS is proposed to minimize the steady state error and to decrease the rising time with no oscillation for current and voltage for whole system. The simulation results demonstrate that the system of MPPT based on FIS-PID is more effective and more accuracy with high efficiency as compared with traditional MPPT for photovoltaic system.
