一种新的多变量自校正解耦控制器的研究

The Study of a New Multivariable Sely-Tuning Decoupling Controller

在解决不相同时间延时的多变量自校正控制问题中,任意交互阵起了重要的作用,但在实际中,交互阵是不容易求得的。本文提出一种当交互阵为对角时的多变量自校正解耦控制器的设计方法。本文把Koivo(1980)推广到了不同时间延迟的系统,并且对加权阵进行了合理的选择。从仿真图形来看,本方法具有良好的解耦特性。

In solving the problem of a multivariable self-tuning decoupling controller in the case of different delaytime , the general interactor matrix plays an important role. In fact, it is no easy to know the interactor matrix.In this paper, a designing method of a multivariable self-tuning controller is proposed when the interactor matrix is a diaganol matrix. The paper extends the system in koivo(80) to the system of different time delay , and reasonably chooses the weightmatrix. The simulation results shows that the method has good decoupling property.
