摘　　要：针对供水、造纸等行业中的恒定水位系统,提出恒定水位控制的控制方案。在分析电机机械特性的基础上,完成了控制系统结构设计,给出了系统中每一部分的传递函数。采用PID调节器作为转速调节器,实现了数字PID调节器的单片机程序,采用归一参数整定法完成了PID参数整定。实验证明,该水位控制系统能够完成恒水位控制,具有成本低,结构简单等优点。A control system which is used to keeping constant level in water tank for industry of water-supply or paper-making is de- signed. The structure of control system is designed based on analyzing mechanical properties of AC motor. And, transfer function of every part is given. PID controller is used as ASR and program whose parameters are normalized is compiled. Tests show that the system can con- trol water tank with constant water-level effectively, and it has advantages of lower cost and simple structure.
