摘　　要：该文以耦联双容水箱为例,介绍了一种基于WinCC的水箱液位控制系统实时仿真平台开发。首先用WinCC构建双容水箱工艺流程动态监控画面;然后在C脚本下实现对水箱液位非线性数学模型的求解和增量PID控制量的计算;最后通过设置相同的采样时间并关联相应的变量,实现监控动态画面和C脚本之间的通信,组建成一个完整的闭环控制系统,并进行手动/自动模式的测试。该仿真平台能够用动画实时地展示水箱液位变化过程,立体感和真实感强,可实现在线修改控制器参数、手动/自动两种模式无扰切换等功能,人机交互效果好,是一个有效的验证各类控制算法及其参数设定的仿真实验平台。Taking the coupled double tank as an example,a real-time simulation platform of water tank level control system based on WinCC is introduced in this paper.Firstly,the dynamic monitoring screen of the process flow of the double tank is constructed using WinCC,and then the solution of the nonlinear mathematical model of the tank liquid level and the calculation of the incremental PID control quantity are realized under C scripts.Finally,by setting the same sampling time and relating the corresponding variables,the communication between the dynamic monitoring screen and the C scripts is realized,so as to form a complete closed-loop control system,and the manual/automatic mode test is carried out.The simulation platform can display the change process of water tank liquid level in real time with animation,with strong three-dimensional and realistic sense.It can realize the functions of online modification of controller parameters,and undisturbed switching between manual and automatic modes,which has good human-computer interaction effect.It is a effective simulation experimental platform to verify various control algorithms and their parameter setting.
