双容水箱液位解耦控制系统的设计

Design of Two-Container Liquid-Level Decoupling Control System

针对双容液位系统关联和耦合问题,采用前馈补偿解耦控制完成静态解耦控制方案,并将解耦方案在计算机中通过编程实现,从而实现双容液位系统的解耦控制。实验结果表明,应用前馈补偿解耦方案控制效果良好,解决双容液位系统的相互关联及耦合,满足系统的控制要求。

Aiming at the problem of two container liquid-level system correlation and coupling problem, this paper completed the static decoupling scheme used feed forward compensation deeoupling eontrol and realized two container liquid-level control system through programming on computer. The experimental results showed that the application of feedforward compensation deeoupling scheme aehived good result.It solved two container liquid-level systems of intercomlected and coupled and meet the requirements of control system.
