介绍一种新的逆向解耦控制方法,该方法中,解耦矩阵各元素的阶次和系统的阶次是相互独立的,不会随系统的阶次增加而变得复杂,因此更适合于高阶系统.首先利用相对增益矩阵方法得到系统的输入输出最佳配对,根据这一配对通过逆向解耦方法构造出逆向解耦控制器,并对该解耦方法的稳定性进行分析和设计,最后通过仿真验证了该逆向解耦控制器的正确性与实用性,并通过和其他解耦控制方法进行仿真比较,得出本方法的优越性.
This paper presents a new inverted decoupling approach that is suitable for high order muhivariahle system. In the inverted decoupler, the decoupling elements is independent of the system size, It is more flexible in choosing the transfer functions of the decoupled process. First, according to the relative gain array (RGA) , the best pairing for input-output can be obtained, then the expressions of the inverted deeoupling are presented for general n x n processes. Second, the stability conditions are stated to select a proper configuration. Finally, the validity can be proved by using several simulation examples, and comparisons with other works demonstrate the effectiveness of this methodology.
