基于模糊PID的煤矿井下排水控制系统

The coal mine drainage based on fuzzy PID control system

提出一种以PLC控制器和矿用隔爆兼本安型变频器为核心的煤矿井下排水系统。在硬件基础上,详细设计出了模糊自整定PID算法,并用Simulink仿真对模糊自整定PID和普通PID算法进行了比较。在荣华一矿实际应用中,当排水系统对不同目标供水时,控制电机转速,使水泵出水口压力满足不同目标的用水需求。通过仿真和实际使用的结果表明,采用模糊自整定算法的煤矿井下排水系统可以快速的响应不同供水压力需求,提高了控制精度,改善了控制性能,达到了节能减排和水资源综合利用的目的。

Proposes a PLC controller and Flameproof and Intrinsically Safe inverter as the core, the practical application of mine Ronghua a background of coal mine drainage system in the living area for mines, fields and coal washing plant, such as different tar-get water , through the fuzzy PID controller, precise control of motor speed, the pump outlet pressure to meet the water needs of dif-ferent target.
