Multi-model control of a boiler-turbine unit is discussed in this paper. Based on the nonlinear model of the unit, this paper applies the gap metric concept to analyze the problem whether a multi-model control is necessary for the unit and select the appropriate operating points accordingly. The multi-model control is then designed based on local coordinated PID controllers. Simulation and the experimental results at Daqi 4# Unit show that the multi-model controller can guarantee the desired performance under wide range of load variations.
