A Temperature Control of Thermal Power Plant Superheater System using Iterative Method |
| Abstract |
In this paper, we construct the controller for the heat exchanger system using iterative method. For applying the linear quadratic control theory to the heat exchanger system which is represented by the bilinear the system, we formulate the system to execute iteration, We also propose Extended Kalman Filter to estimate bilinear system state for purpose of state feedback controller design. We also apply the iterative controller to the thermal power plant superheater steam temperature control, and computer simulation show that the estimated value follows the superheater steam temperature under the variation of the external inputs, and that the output steam temperature is properly maintained. |
