模糊PID自整定技术在地铁空调控制中的应用

Application of Fuzzy-PID Auto-Tuning in Subway Air Conditioning Control

上海地铁车厢内的温差变化较大,导致地铁的空调器件经常损坏.采用模糊比例、积分和微分(PID)自整定控制的方法来降低车厢内温度的波动性,使用Matlab进行仿真,并与传统的PID控制方法进行了比较,取得了满意的结果.

The large change of temperature inside Shanghai Metro carriages can result in frequent damage to air conditioning devices.The auto-tuning technology of fuzzy proportional-integral-differential controller was used to reduce the fluctuation of temperature inside the carriage,simulation model was established by Matlab.Compared with the traditional PID control method,the satisfactory result was obtained.
