Analysing Stability of Time Delayed Synchronous Generator and Designing Optimal Stabilizer Fractional Order PID Controller using Partical Swarm Optimization Technique

This paper investigates designing of optimal fractional order PID controller for a time delayed generator excitation control system. Time delays may result to weaken performance and instability in system. In this research, we aim to design fractional order PID (FOPID) controller for time delayed synchronous generator which preserve performance and make a suitable delay margin for the system. The controller will be designed using Particle Swarm optimization (PSO) algorithm by defining a suitable cost function. At the end, a comparison between results of FOPID controller and PID controller proves advantages of fractional order controller.
