我们提出了一种新的方法参数鲁棒控制器的设计,在这里我们计算控制器的任意阶和结构,最小化最坏情况下的H-无穷范数在一个预先指定的不确定参数。在我们的方法的核心是一个非光滑的最小化方法定制的功能,这是半无限小的光滑函数。一个丰富的测试平台和一个更详细的例子说明了该技术的潜力,它可以处理复杂的问题,涉及多个可能重复的不确定参数。
We present a new approach to parametric robust controller design, where we compute controllers of arbitrary order and structure which minimize the worst-case H-infinity norm over a pre-specified set of uncertain parameters. At the core of our method is a nonsmooth minimization method tailored to functions which are semi-infinite minima of smooth functions. A rich test bench and a more detailed example illustrate the potential of the technique, which can deal with complex problems involving multiple possibly repeated uncertain parameters.
