提出了一种线性和非线性系统稳定化控制器Youla参数化的状态空间方法。镇定控制器（或一类非线性系统的镇定控制器）的特点是稳定参数的分数变换。这种方法的主要思想是将输出反馈镇定问题分解为状态反馈和状态估计问题。参数化输出反馈控制器具有分离结构。这种机器允许参数化的稳定控制器进行直接在状态空间中，而不使用互质分解。>
A state-space approach to the Youla parameterization of stabilizing controllers for linear and nonlinear systems is suggested. The stabilizing controllers (or a class of stabilizing controllers for nonlinear systems) are characterized as fractional transformations of stable parameters. The main idea behind this approach is to decompose the output feedback stabilization problem into state feedback and state estimation problems. The parameterized output feedback controllers have separation structures. This machinery allows the parameterization of stabilizing controllers to be conducted directly in state space without using coprime factorization. >
