Abstract
Resonant compensators appear to be suitable for active power filter control, where the compensator needs to track harmonic currents accurately. However, to ensure stable operation and robustness to parameter uncertainties they require considerable design effort. This paper describes the use of a genetic algorithm for the optimization of the parameters of a resonant controller employed for the control of current in a shunt active filter. The optimization process takes into account variations of the power system parameters to provide an optimum solution in terms of both speed of response and robustness. Experimental results confirm the effectiveness to the approach.
