Research on the fuzzy decoupling in the coordinated control system of nuclear power plant

A fuzzy decoupling strategy with a compensator and a design method for the decoupling compensator are put forward based on the research on the decoupling control theory for a multivariable coupling nuclear power system. The designing method for the compensator is discussed. The fuzzy decoupling and compensating table is designed in detail for the double inputs and double outputs control system. The fuzzy decoupling technology is applied to design of the decoupling compensator for the basic class of coordinated control system of a nuclear power system, and a control system structure is present in the paper also. Under the typical load disturbance, the simulation result shows that the coordinated control system with the fuzzy decoupling strategies is better than the coordinated control system without decoupling strategies, especially good for the steam pressure of steam generator.
