针对具有非结构不确定性的多输入单输出并联结构对象，提出了一种具有鲁棒性的低阶非保守控制器的设计方法。第一步是分析生成增益相位控制器边界，如定量反馈理论（QFT）。然后，为了避免产生高阶控制器的QFT环路整形的困难步骤，将这些边界转换为控制器参数空间，在该空间中进行低定阶控制器的迭代设计。这一点，以及该技术提供的设计透明度，构成了明显优于其他流行的/spl mu/-合成的稳健性能设计方法的优势。其他重要的特点是，所提出的方法没有引入额外的保守性，并且该方法与顺序循环关闭策略直接兼容。最后，任何额外的次要条件的直接搜索优化是可能的。
This paper presents a method for the design of nonconservative low-order controllers achieving robust performance in the case of multi-input single-output parallel structure plants subject to unstructured uncertainty. The first step is the analytical generation of gain-phase controller bounds, as in quantitative feedback theory (QFT). Then, to avoid the difficult step of QFT loop shaping, which often produces high-order controllers, these bounds are translated into the controller parameter space where the iterative design of low fixed order controllers takes place. This, as well as the design transparency offered by this technique, constitutes appreciable advantages over the other popular robust performance design method of /spl mu/-synthesis. Other important features are the fact that no extra conservatism is introduced by the method presented and the fact that the method is directly compatible with a sequential loop closing strategy. Finally, the direct search optimization of any additional secondary criteria is possible.
