Research and application of fuzzy FO-PID predictive function control algorithm

In order to overcome the defect that FOPIDPFC algorithm parameters cannot realize self-organizing adjusting online and to improve the generator operating stability to acquire higher precision, fuzzy control algorithm combined with FOPIDPFC algorithm is adopted to implement PIDPFC control parameters online self-organizing adjusting by using fuzzy logical control and to consummate common FOPIDPFC controller. This fuzzy PIDPFC control algorithm was applied to synchronous generator excitation system. Results through MATLAB simulation confirm that, compared with FOPIDPFC and PIDPFC control, the fuzzy FOPIDPFC controller shows better controlling ability. System under the control of the FOPIDPFC shows better dynamic and static performance. Testing in the power system dynamic simulation laboratory gets the same results as the simulation.
