In this paper, a method has been proposed for better tuning of the parameters of Fuzzy PID.
The work also proposes a modified firefly optimization algorithm for generating the values of

In this paper, a method has been proposed for better tuning of the parameters of Fuzzy PID. The work also proposes a modified firefly optimization algorithm for generating the values of the Scaling Factors for the Fuzzy PID. The performance of the proposed configuration is evaluated through extensive simulations. The result reveals that the proposed scheme converges significantly faster and performs better over conventional PID controller and existing Fuzzy PID controllers in terms of several performance indices, such as, overshoot, settling time for the plant and integral square error (ISE).
