摘　　要：某化学分析仪器需对处理过程进行温度控制,控制涉及多个部位,各部位加热器效率并不相同,并且每个控制点在不同的处理流程中存在不同的目标温度。为解决上述问题,采用PID控制和模糊控制相结合的自适应温控方法,根据被控系统的实际响应,运用模糊推理,考虑各加热器的效率,目标温度与环境温度差等因素,实现温控过程中PID参数的自适应调整。采用上述控制方法,对该分析仪器5个加热箱进行了全工作流程的温度控制,实现了系统设计目标。应用结果表明,所述控制方法对加热器效率不同,控制过程中目标温度发生改变的温控系统可实施有效控制。A chemical analysis equipment needed to control the temperature of different parts which have different heating efficiency.And every part have different desired temperature in different chemical analysis processing.In order to solve these problems,an adaptive technology of control different temperatures in different parts with a combination of PID and fuzzy control is adopted.According to the actual response of the controlled system,by considering the efficiency of the heater and the target and the environmental temperature,the PID parameters adjustment is realized in different chemical analysis processing.The application results show that the PID control method for different heater,temperature can be implemented in different control objectives.
