| Abstract: | An adaptive control scheme, with low computational requirements, applied to controlling the excitation of a synchronous generator is described in this paper. The adaption scheme adjusts the feedback gains of linear controller to improve the performance of system from operating point to operating point. Computer simulations are used to compare the response of the adaptive excitation controller with that of a linear optimal controllet. It has heen shown that the designed controller provides effective damping torque for power system and yields better system dynamic performance than that obtained by using linear optimal control. |
