The intelligent compound controller used in thermal power unit coordinated control system

A new intelligent control method is presented for a unit coordinated control system in this paper. By an analysis of the dynamic characteristic of the unit, the intelligent compound controller is proposed for the problems in the system, such as the responding rate being slower for the goal load and the overshoot higher. The new controller that is employed in the coordinated control system of the thermal power unit is combined with fuzzy rules, the traditional feedback and feedforward controller and its parameters are tuned by the fuzzy rules. The simulation results and actual operation performance show that the control performance is improved. The ability of tracking and anti-jamming is enhanced, and the dynamic overshoot is decreased. It is in favor of the safety and stability of the unit.
