The unit Coordinated Control System based on the fuzzy neural network inverse control method

According to the performance of fossil fuel-fired units, that profound coupling nonlinearity and which made the mathematical model very difficult. Inverse method control for the design of MIMO system of unit coordinated control system is suggested. the realization of the inverse system up is not adopt traditional meaning is of the obvious analyze, but adopt the dynamic neural network, the inverse system that construct to non-analytical model, combine the neural network inverse system and the linear PID control to construct closed loop system, apply in the boiler-turbine coordinated control system. Through simulation testing, this kind of new control method not only has the satisfied control performance, but also has the stronger robustness and interference resistance, improve coordinated control system of fossil fuel-fired units altering operating mode of adaptability and the control quality.
