PID参数自整定在恒压供水控制器中的应用

Application of self-tuning PID parameters in constant pressure water supply controller

传统的恒压供水控制器通常采用PID调节器,其算法难以编程实现,并且调试困难。将自整定PID调节器应用到恒压供水控制器中,这样,用户就不必调整PID参数,从而大大方便了现场调试,并保证了系统的长期稳定性。

Traditional constant pressure water supply controller usually adopts PID adjuster. The difficulty of its arithmetic programming is too high and its debugger is also difficult. The paper introduces self-tuning PID parameters adjuster into constant pressure water supply controller, thus users needn＇t adjust PID parameters, which is convenient for the field-debugger and also ensures long stability of water supply system.
