摘要
针对集中供热系统中的热工过程对象(如换热机组)具有大惯性、大时滞、时变和非线性等动态特性,建立了它的CARIMA模型和基于该模型的供水温度广义预测控制系统。利用Matlab对该控制系统进行了仿真。结果表明:广义预测控制(GPC)可以应用于热工过程控制中,并能取得良好的控制品质和鲁棒性。
Aimed at the dynamic characteristics with large inertia,large pure delay,time- varying and nonlinear etc.of the thermal processing plant in central heating system,such as heat-exchange units in the thermal station ,its dynamic mathematical model and water supply temperature of the model-based generalized predictive control system are developed.Software Matlab is used to perform the simulation investigation of this control system.Simulation has powerfully proved that generalized predictive control can be applied to thermal processing control and get good control quality.
