Youla参数化方法广泛应用于控制系统的分析和设计；此方法使得系统闭环稳定的全部的镇定控制器均以一个稳定传递函数作为待定参数来表达;建立另外一种不同的参数化方法,这种方法尤其适用于主动振动控制系统:它不仅参数化所有镇定控制器,同时能够给控制性能变量以非常直观的几何图形解释；讨论这种新方法的特性及其设计,并将该设计方法应用于一个三自由度的主动振动隔离系统中,仿真结果表明,所提出的方法可以有效地达到主动振动隔离的设计目的.%Youla-Parameterization has been widely utilized in control system analysis and control system design. In this approach, all stabilizing controllers are parameterized by a stable transfer function. However, there also exists a different parameterization approach and when applied to scalar feedback active control systems, it possesses remarkable properties: it not only parameterizes all stabilizing controllers, but also parameterizes performance variables that allow a geometric interpretation. This note aims to discuss the properties of this novel approach and its design as well as limit of performance implications. The resulting design methodology is also illustrated by its application to a three-degree-of-freedom active vibration isolation system, validating the effectiveness of the proposed design methodology.
