Boost converter control by using of FOPID optimized by ICA

This paper proposes a new method for designing fractional order PID to control boost converter. FOPID is a PID controller where the integration and derivation orders are of fractional order rather than integer. In this paper FOPID controller is used for controlling the boost converter, and Imperialist Competitive Algorithm is employed to determine FOPID parameters because of its good performance and high accuracy. To illustrate the performance of the proposed controller, some simulations have been carried out in MATLAB and the results have been compared with Genetic algorithm. Moreover, FOPID controller has been compared with PID and PI controllers optimized by ICA. The Simulation results illustrate the good performance of the proposed controller.
