针对带宽资源有限的网络化控制系统,提出一种切换控制策略.基于Lyapunov第二方法引入衰减系数的概念,在此基础上给出保证单个系统稳定的最小网络通讯间隔以及保证多系统同时稳定时网络通讯间隔应满足的条件.本文的方法实质上也是一种网络环境下多任务的调度方法.
Switching control strategy of networked control systems was brought forward in view of the bandwidth limitation of network. Based on the 2nd Lyapunov method, a notion of decay coefficient was incroduced. Then, the condition of minimal network communication interval which should be met by both the stable single and multi-systems was given. In fact, the method presented could also be regarded as a scheduling method for multi-tasks under network environment.
