Abstract :
The main steam system of boiler is typical time delay process. The steam temperature of superheater is an important parameter that must be kept in a certainty range when the unit plant is running. According to the characteristic of the process, the paper introduces a new type of robust PID controller that can assure stability when parameter and time delay are mismatched with the controller. Simulation result shows that the control effect is very well.
