基于多模型切换的过热汽温智能控制

Study of Intelligent Superheated Steam Temperature Control Based on Switching of Multiple Models

针对火电厂过热汽温控制系统具有大迟延、时变等特点,常规控制难以取得满意的控制效果,提出了基于多模型切换的过热汽温智能控制方法。仿真结果表明,过热汽温控制的动态特性明显得到改善。

Superheated steam temperature control system in thermal power plant features long time delay and time-varying, for which the conventional control strategy generally can’t satisfy excellent control effects. Intelligent superheated steam temperature control based on switching of multiple models is presented. Simulation results show that the new control strategy has better dynamic characteristic than single model system.
