Optimal design of PIDA controller using firefly algorithm for AVR power system

In this article, a new proportional, integral, derivative and acceleration (PIDA) controller is presented and designed for an automatic voltage regulator power system. The controller parameters are designed by considering as an optimization with minimization of square error using firefly algorithm. The response of the firefly algorithm optimized PIDA (PIDA-FFA) controller are observed and compared to the controllers in literature. The superiority is validated in terms of performance indices (ITAE, IAE and ISE).
