摘要: 本文设计了用于多种控制算法研究的液位实验系统, 包括液位控制实验装置、通讯硬件和
上层控制软件. 通过液位控制实验装置回路和阀位的不同组合, 能够使被控对象具有多变量、有
耦合、有干扰、多种工况等各种情况. 通讯硬件完成串口通讯和信号 A/ D, D/ A 功能. 上层控制软
件采用 VC ++ 编程语言, 其中控制算法作为一个独立的模块, 易于修改或加入各种控制算法. 该
系统集成度高、功能完善, 界面友好. 实验实例结果表明该系统是验证多种控制算法的良好实验
平台.

Abstract:
A liquid level process control system is designed for the purpose of control algorithm research in
this paper, including liquid level tank device, communication hardware and control software. By bi
nation of the different loops and valve position, the system is a multivariable, coupling, disturbance and
multiple working condition controlled object. Communication hardware has the function of munica
tion, signal A/ D and D/A. Control software is programmed by VC++ , and control algorithm is an inde
pendent module, and revise and add of control algorithm is easy. The control system has high integration,
perfect function and user
