摘　　要：过程控制实验系统在高校和科研中应用比较广泛,双容水箱液位控制系统具有单输入、单输出、非线性、时变和滞后性的特征,本文以天煌教仪THJDS-3型过程控制实验平台中的双容水箱液位作为被控制对象,通过该系统建立双容水箱液位的传递函数数学模型,设计了PID控制器,并用MATLAB对上述控制系统进行了仿真研究,对实验结果进行了分析。The process control experimental system is widely used in Colleges and universities and scientific research.The double tank liquid level control system has the characteristics of single input,single output,nonlinearity,time-varying and hysteresis.This paper takes the double tank liquid level in the thjds-3 process control experimental platform of Tianhuang teaching instrument as the controlled object,and establishes the transfer function mathematical model of the double tank liquid level through the system,The PID controller is designed,the above control system is simulated with MATLAB,and the experimental results are analyzed.
