Design of Phase Compensation for Solar Panel Systems for Tracking Sun

The compensation for solar panel systems in order to tracking sun has been studied and represented in its equivalent closed loop control system. These systems improved the performance of solar panel systems to produced maximum power efficiency. The response of this controlled system showed sluggish performance. Therefore, it is necessary to introduce proportional derivative integral (PID) controller and (Lead-Lag) phase compensator to improve the dynamic response of the system. The required specifications are to obtain faster response with the minimum peak overshoot (Mp). The closed- loop system is initially built in Simulink/Matlab package and the (PID) controller and (Lead-Lag) phase compensator has been build into special subsystem. The components of control system have been dragged directly from Simulink library. Results showed that when compensator is properly designed the response would be acceptable in the sense of required specifications.
