Abstract:

This paper presents a design and simulation of simplified method for designing a proportional – integral–derivative(PID)controller operating in continuous conduction mode for the Buck-Boost converter ,this method provides good voltage regulation and is suitable for Buck-Boost Dc-Dc converter, it is exposed to significant variations which may take this system away from nominal conditions caused by the line change and parameters variation at the input .Simulation results shows that this PID controller provides good voltage regulation and is suitable for the Buck-Boost purposes. The obtained results prove the robustness of proposed Controller against variation of the input voltage ,load resistance and the referent voltage of the studied converter.
