State Feedback Control and Applied to PV Systems Under Improved MPPT Control

In this paper, a state feedback closed-loop system with integral control is proposed for photovoltaic system output voltage regulation. Where P&O algorithm is used to control the voltage output. In order to verify the control scheme, it was applied to DC - DC converter boost type to improve its dynamic performance, and apply the improved system to the maximum power point. The proposed method is tested by computing simulation in Matlab/SIMULINK environment. The results show that the control technology can be applied to DC/DC converters and adjust the output voltage, then the validity of the technology is confirmed.
