Waste incinerator is difficult to control since the composition of solid refused fuel (SRF) can change randomly under certain specification. In this study, a model-based controller was designed for waste incinerator and steam generator by using linear-quadratic regulator (LQR). Input variables were chosen as air and fuel supply rates, and output variables were steam flow rate and oxygen concentration of exhaust gas, thus requiring a multi-input multi-output (MIMO) control scheme. Control gain matrix was evaluated repeatedly at each time step based on nonlinear control model, which could predict the output variables covering the range of operations for the incinerator plant installed in Ul-San-Si. Then, the controller was applied to the developed plant model, which was validated with the experimental data of the designated plant. As a result, the disturbance on the system was effectively rejected, and steam production rate could be controlled to achieve the desired values.
