基于参数自整定模糊PID控制的恒压供水系统

Water Supply System of Invariable Pressure: An Illegible PID Control of Automatic Preferences

从硬件和软件两方面详述了以89C 51单片机作为恒压供水控制系统的核心部件,采用模糊自适应P ID参数控制算法构成的实用恒压控制系统。通过自动整定P ID的参数Kp、Ki、Kd,使P ID控制器能够通过改变输出电压来控制执行机构变频调速器的频率,从而使整个供水系统保持给定压力。

This paper recounts the water supply system of invariable pressure particularly using the singlechip of 89C51 as the central component and adopting illegible automatic suitable PID parameter control arithmetic from hardware and software. The PID controller can coutrol the frequency of transducer of control implement unit and make the water supply system keep the pressure as the input via adjusting the parameter Kp, Ki, Kd of PID automatically.
