多模型块结构Laguerre函数预测控制在再热汽温系统中的应用
Multiple model block Laguerre function predictive control and its application in reheated steam temperature system
摘要
Abstract
In order to reduce the heavy computing load of traditional predictive control and solve the problem of nonlinearity for the controlled plant,a new multiple model block Laguerre function predictive control (MMBLFPC) was proposed and applied to a reheated temperature system of supercritical power plant.Aiming at the poor economy of the practical reheated temperature system,a new cost function integrating with economic performance was proposed by improving the objective function of traditional predictive control.The simulation results show that the MMBLFPC method can completely close the spraying water valve to increase unit economic performance.All of the control performances of different load points are good and the computing load is obviously reduced.Furthermore,the engineering application results show that by this control method the fluctuation range of the reheated steam temperature is decreased,and the flow of spraying water is reduced,thus the safety,stability and economy of the reheated steam temperature system are improved.关键词
