摘要：
An optimizing control system for improving the load following capabilities of power plant units has been developed. The system is implemented as a complement producing additive control signals to the existing boiler control system, a concept which has various practical advantages in terms of implementation and commissioning. The optimizing control system takes into account the multivariable and nonlinear characteristics of the boiler process as a gain-scheduled LOG-controller is utilized. Simulation results indicate that a reduction of steam temperature deviations of about 75% can be obtained. Copyright (C) 1998 IFAC.
