摘　　要：链篦机焙烧温度场优化控制是关于链篦机的主要研究方向之一,但在链篦机温度场模型中参数较多且多变,而目前关于链篦机焙烧温度场优化控制的仿真研究大多是在固定参数的条件下完成的,不能很好的反应实际情况。为了准确的反映链篦机运行的实际情况,实现多参数变动下温度场的优化控制,首先对链篦机温度场的机理分析,提出了一种有限差分法求解温度场优化控制模型的方法,并通过Lab VIEW与MATLAB的混合编程进行了仿真验证。仿真结果表明改进模型的输出准确性较高,并且能够通过Lab VIEW前面板实时的修改参数,有效地增加了实用性,为焙烧温度控制提供了科学依据。Optimal control of the temperature field of chain grate is the principal direction of research about chain grate. Most of the parameters of chain grate are changed. But at present, most of the optimal control of it do not consider the changed parameters. The actual situation cannot be reflected. In order to establish an accurate control with changed parameters, a new optimal control method of the temperature field of chain grate is proposed. First, the mechanism of the temperature field of chain grate is analyzed. Then, the simulation model is established is established by finite difference method. The simulation is study by mixed programming of LabVIEW and MATLAB. The simulation result shows that this model has high accuracy. The parameters can be changed by front panel of Lab- VIEW, and the practicability is increased.
