摘　　要：一本文针对用于惯性元件测试的数字式温度控制系统，从传热学原理出发，推导出了该系统温控箱的差分模型结构，并通过大量的实验确定了模型系数波动范围及均值；由此提出了一种较实用的自适应ＰＩＤ方案，改进了原有的常规ＰＩＤ控制器。仿真结果表明，改进的温控器较原控制器有较强的适应性。In this paper an adaptivc PID control algorithm is proposed for the temperature controlled system which is designed for temperature experiment of inertial units.According to the heat-conducting principle , the difference model structure of the temperature controlled box is reasoned out. Coefficients of this model are identified through many experiments. Based on the model, a practical adaptive PID control aigo-rithm is put forward.Simulation results show that the improved controller is more adaptable than the conventional PID controller.
