研究了一类单输入单输出时滞系统的稳定次优H ∞控制器。对于给定的对象和加权函数，最小化混合灵敏度的最优控制器（和中心次优控制器）可能是不稳定的，在C++中有无穷多个极点。对于这些情况下，搜索算法，提出了找到稳定的次优H ∞控制器。并以实例说明了这些设计方法。
This paper investigates stable suboptimal H-infinity controllers for a class of single-input single-output time-delay systems. For a given plant and weighting functions, the optimal controller minimizing the mixed sensitivity (and the central suboptimal controller) may be unstable with finitely or infinitely many poles in C+. For each of these cases, search algorithms are proposed to find stable suboptimal H-infinity controllers. These design methods are illustrated with examples.
