含参数不确定性系统的鲁棒性能设计

讨论含有参数不确定性系统的鲁棒性能设计问题。首先将该问题转化为一个多项式簇的鲁棒稳定性问题，从而得到鲁棒性能控制器应满足的频域充要条件，然后通过一个双回路控制器的设计将鲁棒镇定和鲁棒性能设计分两步进行，使设计条理化、简单化。

Robust Performance Design for Linear Systems with Parametric Uncertainties

In this paper, the problem of robust performance design for linear systems with parametric uncertainties is studied. First, the problem is changed equvilently to the problem of robust stability of uncertainpolynomials with complex coefficients. Then, the necessary and the sufficient conditions on the frequency domain for the controllers are provided. Furthermore, to simplifying the design, a procedure of the two-loop controllers design is introduced. Then the robust stabilization and the robust performance design can be solved step by step.
