A Novel Control Method for Drum Level and Pressure Basing on Dynamic Surface

초록

영어

A novel drum level and pressure simultaneously control method is developed using the dynamic surface control method in this paper which takes account of the output power of units and load change .Certain first-order low-pass filters are introduced into the designing process to avoid the occurrence of high-order derivatives of elements in the system which makes it easy to implement in practical applications. The proposed control method is effective in compensating for the disturbance of load and fuel. Simulation results show that the dynamic surface control method still ensures an accurate result, even if the loads change in a great and parameters of the controlled plant change significantly.
