The advanced control strategy can enhance the control quality of thermal power unit

but the traditional PID regulator can't be easy to reach good control effectiveness due to multiple variables and strong coupling problems existing in the coordinated control system of unit.For this

a mathematical model has been established by adopting the generalized prediction control algorithm with decoupling.Results of emulation show that the control effectiveness of coordinated control system based on generalized prediction control algorithm is obviously superior to the commonly generalized prediction system

having load-disturbance resisting capability and strong robustness

being suitable for system with time delay and with other stronger couplings.
