尝试用LMI技术解决状态反馈H/sub //H/sub /spl //控制问题，该技术允许罕见的LMI解。为了获得一个保证两个性能标准的通用控制器，同时允许不常见的LMI解决方案，我们计算出LMI解决方案的哪一部分应该被约束。然后，利用无约束部分的自由度，我们提出了一种迭代方法来获得更新的控制器增益，进一步提高了在/spl Hscr//sub /spl infin//约束下的H/sub / 2/性能。包括一个图解示例。
Attempts to solve the state-feedback H/sub 2//H/sub /spl infin// control problem by a LMI technique that allows for uncommon LMI solutions. In order to obtain a common controller ensuring the two performance criteria while allowing uncommon LMI solutions, we figure out what portion of the LMI solution should be constrained. Then, utilizing the freedom of the unconstrained portion, we propose an iterative method to obtain an updated controller gain which further improves the H/sub 2/ performance under the /spl Hscr//sub /spl infin// constraint. An illustrated example is included.
