Generalized Predictive Fuzzy Control of Coordinated Control System of Thermal Power Plant

In view of the nonlinearity and coupling in the coordinated control system (CCS) of thermal power plants, the paper introduces a Takagi-Sugeno (T-S) fuzzy model based generalized predictive control (GPC) of CCS. First, a T-S fuzzy model with three chosen typical operating point is employed to approximate the nonlinearity of the CCS of the thermal power plant. Then, based on the obtained T-S fuzzy model, a GPC controller is developed to achieve a desired performance. Finally, a living example of a 330MW thermal power unit is used to demonstrate GPC controller.
