Abstract
With the development of the national economy, the demand of electric power market has become higher than before. The stable and reliable power system is one of the important national economic securities. Reliability of generator excitation system is one of the important elements to determine the stability of the power system. Traditional PID cannot meet the requirements of the increasingly complex power system due to some defects. This essay introduces FLC control, combining with the traditional PID control. Using Matlab software, we analyze the curve and FLC is better than that by comparing with the traditional PID.

Summary
Generator’s excitation control is a typical non-linear time-variant control system. Due to the complexity of the electric power system, the demands towards the generator’s excitation control system have been constantly enhancing. With the development of the control theory, it is a trend of development that the integration of the intelligent control theory and generator’s excitation control can achieve a better effect of control. The traditional PID control structure is simple, has a certain robustness, and can achieve better control effect, but because the traditional PID controller needs to manually adjust the parameters, so that the generator excitation adjustment process is more complicated and inconvenient. Some defects of the traditional PID excitation control are proposed, and the control of generator excitation system based on FLC is proposed.
