摘　　要：就数值寻优和仿真方法在热工过程中应用的几个问题作了讨论，提出了在热工仿真中加阀门开度限的方法，并把超调指标限制引入参数寻优过程，使寻优参数除满足指标函数最优外兼顾了其他控制品质。The paper deals with the application of optimization and simulationin the thermo-system control. It gives a method to simulate the span of valve opening. It also introduce a way to make the parameter fullfil both the target function and the limit of overshoot. It discusses the way to simulate precision of the sensor and the means to solve the problem which happens when the simulation precision decreases against the digital computer's precision increases.

关 键 词：仿真 指标函数 阀门开度 超调量 热工系统
