Carlos M. Massera, Marco H. Terra, Denis F. Wolf

摘要:

针对具有范数有界结构参数不确定性的离散线性系,提出了状态反馈和静态输出反馈广义保成本控制(GCC)方法.这种方法使得凸综合的更一般的系统,其中不确定性是不相关的块对角,并没有馈通不确定性与控制输入的乘法。给出了状态反馈的充要条件和静态输出反馈的充分条件。我们还提出了一个比较研究之间的建议控制器,标准的线性二次型调节器,并在文献中发现的保成本控制器。

英文摘要:

In this paper, we propose state- and static output-feedback generalized guaranteed cost control (GCC) approaches for discrete-time linear systems subject to norm-bounded structured parametric uncertainties. This method enables the convex synthesis for a more general class of systems, where uncertainties are uncorrelated block diagonal, and no feed-through uncertainty is multiplicative with control input ones. It also provides necessary and sufficient conditions for state-feedback and sufficient conditions for static output-feedback. We also present a comparative study among the proposed controllers, standard Linear Quadratic Regulator, and Guaranteed Cost Controller found in the literature.
