摘　　要：针对GIS微水监测湿度传感器在线校验要求,设计了一种湿度传感器的自校验平台。该平台的设计依据拉乌尔定律,通过模糊控制对比例一积分一微分(PID)的3个参数K_p,K_i,K_d进行在线自整定,并输出脉冲宽度调制(PWM)进行温度控制,从而标定湿度值。仿真和实验结果都表现出使用模糊PID控制能使系统达到令人满意的控制效果,对后续的湿度传感器校验有较大的应用价值。In this paper, the author designs a kind of adaptive equipment to experiment the humidity sensor of moisture content in GIS. The design of this equipment is based on Rauh＇s law. By using fuzzy control technology ＆ adjusting the three parameters Kp,Ki, Kd of PID controller on-line, PWM can be outputted to control the temperature and produce tile humidity source. The results of simulation and experiment indicate that the fuzzy PID control gives us a good control performance and has a high reference value for further experiments of humidity sensor.
