کنترل بهینه فیلتر توان اکتیو با استفاده از کنترلرهای سفارش اعشاری بر اساس روش بهینه سازی NSGA-II

Elitist Non-Dominated Genetic Algorithm (NSGA-II) optimization method offers optimal solution to multidimensional objective functions. In this paper, this optimization method is used for designing Fractional Order PI controller that features a better performance than the Integer Order PI controller for improving the performance of a Shunt Active Power Filter. Controller synthesis is based on required Total Harmonic Distortion and transient specifications. The characteristic equation is minimized to obtain an optimal set of controller variables. This process is done by using the Integer Order PI controller and Fractional Order PI controller with the high performance Repetitive Controller. Simulation results are obtained by using the Fractional Order PI controller are better than the ones are obtained by using the Integer Order PI controller.
