The Application Of Neural Network And Fuzzy Network And Fuzzy Control In The Coordinated Control System

The coordinated control system (CCS) for boiler-turbine unit is a complicated multi-variable control plant. It has some characters such as nonlinear, parameters time varying and large delay. The control strategy of conventional coordinated control system is far from responding to the request of the electric network. Based on the fuzzy control and neural network theory, this paper found a combing point of them and introduced a fuzzy controller of parameters of self-adjustment based on BP neural network and used it in CCS and did a great deal of simulation work. We can get the result: the control method in this paper has good control quality. The paper supplied a new thinking to research multi-variables control system and have certain theory meaning and project using value.
