一种新的多变量参考模型解耦控制的方法

A Reference Model Decoupling Method for Multivariable Systems

为了能使解耦控制和主回路控制相互独立,同时改善动态和静态解耦特性,提出一种新的参考模型解耦方法。参考模型回路由控制器和被控对象的传递函数2部分组成,而不是一般意义上的只由单一的参考模型传递函数构成。解耦控制器被引入到解耦环节,使解耦与主回路控制独立,控制与解耦功能分别由2个不同的控制器独立完成。控制器的设计非常简单、方便,不会顾此失彼。以性能指标逼近的方式,该方法基本上能实现动态和静态的解耦。通过对实际工业系统的仿真,取得了良好的解耦效果。

To separate the decoupling controller from the main controller and improve the decoupling performance, a reference model decoupling（ R, MD）method for muhivariable systems is provided. Reference model consists of the controller and the transfer functions of controlled object instead of well-known single reference model transfer function. Decoupling controllers are introduced to decoupling devices to realize the independence of controlling and deeoupling. Decoupling design turns to be very simple and the complete decoupling performance can be obtained. The simulation result shows the decoupling capability.
