Abstract
the present work has been motivated to improve the tuning of PID controllers with different evolutionary algorithms. The tuned PID controllers are used along with the Automatic voltage regulator to improve the terminal voltage response of the synchronous generator. The terminal voltage has been analyzed using environment of MATLAB and the responses are compared. The various algorithms used for the analysis of the controllers are the genetic algorithm, the whale optimization algorithm the water cycle algorithm and the particle swarm optimization algorithm.
