Gas turbine generators are normally used in isolated operation. Load fluctuations could cause these generators to become unstable. An effective control and design are required to maintain system stability. The PID controller has been designed using Ziegler-Nichols’ method (ZN) and Genetic Algorithm. The Fuzzy Logic controller is also designed and compared with conventional PID controller. It is shown that by fuzzy logic controller, optimal time domain performance of the system can be achieved.
