针对一大类网络调度协议，给出了网络控制系统的输入输出L/子p/稳定性的结果。结果表明，静态协议和最近提出的一种称为一次尝试丢弃的动态协议都属于这类协议。我们的结果为生成新的调度协议提供了一个统一的框架，如果选择一个足够小的设计参数，这些协议可以保持系统的L/子p/稳定性。我们的结果的最一般版本可用于处理具有数据分组丢失的NC。网络控制系统的模型，特别是我们使用的调度协议的模型似乎是新颖的，我们相信它将在这些系统的进一步研究中有用。我们使用的证明技术是基于小增益定理的，它易于解释。我们证明了我们的结果肯定比文献中已有的结果更好，并通过一个间歇反应器的例子来说明这一点。
Results on input-output L/sub p/ stability of networked control systems (NCS) are presented for a large class of network scheduling protocols. It is shown that static protocols and a recently considered dynamical protocol called try-once-discard belong to this class. Our results provide a unifying framework for generating new scheduling protocols that preserve L/sub p/ stability properties of the system if a design parameter is chosen sufficiently small. The most general version of our results can be used to treat NCS with data packet dropouts. The model of NCS and, in particular, of the scheduling protocol that we use appears to be novel and we believe that it will be useful in further study of these systems. The proof technique we use is based on the small gain theorem and it lends itself to an easy interpretation. We prove that our results are guaranteed to be better than existing results in the literature and we illustrate this via an example of a batch reactor.
