Abstract :
Considering the characteristics of time delay, large inertia and time-varying in superheated steam temperature system, the internal model control (IMC) method based on multiple models is suggested. Every model of the model family is created by practical tests with different load. Their corresponding internal controllers are designed. The output of the general controllers is gotten by calculating the sum of the product of the output of every sun-controller and its weighted factor. By this way, the adaptive control of the total operating conditions is realized. The simulation results show that the control strategy has better control performance than the conventional internal model control.
