摘要
对 Gahinet提出的 H∞ 最优性能指标的不连续性进行了分析 ,指出这不连续性是由于 H∞ 控制器的存在条件不同和可能的零极点对消造成的 .还指出 ,方法不同并不能改变设计中存在的问题 ,对奇异 H∞ 问题 。
The discontinuity of νopt as presented by Gahinet is analysed in this paper. It is pointed out that this phenomenon is caused by the different existing conditions for H∞ controllers and/or the possibility of pole/zero cancellation in the design. It is also pointed out that the computing method itself can not change the essential difficulties in design. For singular H∞ problem, a dedicated approach is still needed.
