For turbine regulating system time-varying and non-linear , the paper proposes a fuzzy adaptive PID control strategy , according to the deviation and the deviation of the rate of change through fuzzy inference adjust PID parameters online . The control strategy lies in the realization of the fuzzy inference system . Fuzzy inference system design , especially to control the design of the rule base , often using the method of constantly trying to spend a lot of time , so the paper presents a particle swarm optimization algorithm automatically generate control rule base . On this basis , this paper, fuzzy adaptive PID control strategy is applied to the turbine governor and simulation studies under different conditions point frequency disturbance . The study showed that , compared with conventional fixed PID parameters control algorithm , fuzzy adaptive PID control better control , and robustness , and prove that this new control strategy is effective . In addition, the fuzzy adaptive PID control strategy can be realized on the PCC and the achievement of the way .
