A Study on Dynamic Matrix Control using Spray and Damper to Once-through Boiler Steam Temperature

In this paper, we present simulation results of Dynamic Matrix Control (DMC) to a Once-through boiler steam temperature. In order to control the steam temperatures, we choose spray and damper as two input variables. Then, the step response model is generated for the two major output variables by step test. After that, on-line optimization is performed using step response model. Proposed controller is applied to the APESS (Doosan company`s boiler model simulator) and the simulation results show satisfactory performance of proposed control.
