摘　　要：结合对温度、压力实验设备的高温、低温及低气压等试验要求,设计并实现了计算机分布式(DCS)的温度、压力控制系统。利用COM技术构建了整个测控系统的软件。为了解决系统超调与响应速度之间的矛盾,以达到更好的控制效果,在经典PID调节的基础上,提出采用专家控制策略控制环境模拟舱内的温度,并对其控制效果进行了仿真研究。仿真结果与现场运行调试结果均表明:专家控制方法具有无超调、响应速度快、稳态精度高、加温效率明显的优点,是可行和有效的,对以计算机为核心的温压控制系统具有借鉴意义。Taking account of the necessary conditions of the temperature and pressure experiments, a distributed temperature-pressure measurement and control system was designed and realized, which could be used to control the temperature or pressure of environmental simulation cabin, of which the software was implemented by using COM technology. To solve the contradiction between system overshoot and speed of response, and get better performance, an expert control method was introduced into this temperature-control system based on the classical PID control theory. Comparing the simulated result with the experimental data, the expert control method has been proved with the advantages of no-overshoot, fast response, high precision and great efficiency. It is significant to the same system.
