Abstract

For the purpose of overcoming the influence of process nonlinearities absolutely and improving the load-following capability, aiming at the typical model of boiler-turbine coordinate system and based on nonlinear method of backstepping, some dummy variables are introduced to construct the Lyapunov function of error signals. A nonlinear coordinated controller for boiler-turbine units is designed. The dynamic performance, disturbance rejection, and robustness, are proved by 3 simulation tests in different operating points.
