讨论了用扩展H∝控制方法来处理描述系统(descriptor system,简记为DS)的非标准H∝控制问题,证明了解存在充要条件,并通过求解两个广义代数Riccati方程(GARE)的准容许解,给出了DS扩展H∝控制器集合。 相似文献

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 ,还需要采用另外的措施才能解决 相似文献

The lifting technique is now a well recognized tool for H1 design and analysis of sampled-data systems. However, the efficiency of the method depends on the structure of the problem. The structure of the H1 sensitivity problem is analyzed in this paper. And the constraints on the H1-optimization problem and on the design parameters in lifting design are also discussed. Under such constraints the resulting performance from the design is generally low. Therefore, the lifting technique can not be recommended as a synthesis tool for the sampled-data systems. An example is also given in the paper. 相似文献
