摘　　要：以PLC系统为工具,实现了双容水箱液位控制。在对水箱模型进行数学分析的基础上,除常规PID控制方法之外,增加了分段控制和PID自整定等优化措施,达到快速且稳定的控制效果。实际控制效果表明,此方案可极大地提升控制品质。此项目的实施验证了该PLC系统可在实际应用中满足实时性、可靠性与易用性的要求。This paper takes PLC system as a tool to control the liquid level of the double-tank water system. In addition to the regular PID control method,this project also fulfills some optimize methods,such as the phase control and auto-tuning PID,so as to control it rapidly and steadily. The actual control results show that this scheme can greatly improve the quality of control. This project proves this PLC system can achieve the requirements of real-time,reliability and usability.
