摘　　要：本文提出了一种新的多变量自适应解耦控制器.该控制器将解耦补偿器与最小方差技术相结合,可以对闭环系统实现动静态解耦.应用本文提出的自适应解耦控制器和常规 PI 控制器分别在某二元试验精馏塔上进行了组分控制实验.实验结果表明,本文提出的自适应解耦控制器的控制性能明显优越于 PI 控制器.This paper presents a new multivariable adaptive decoupling controller which combines a decoupling compensator with generalized minimum variance tech- nique.It can decouple the closed-loop systemes both dynamically and at steady state.The experiments on a pilot binary distillation column were carried out using the adaptive decoupling controller proposed and a conventional PI controller.The experimental results show that the adaptive decoupling controller proposed has ob- viously better control performences than the PI controller.
