Summary:首先,提出一种将优先级调度与通信序列相结合的类最小二乘调度（ LSLS）算法。在每个采样周期内,传感器的测量值传送给LSLS调度器,LSLS调度器将由调度序列确定的测量值与当前时刻调度器内部的理想动态的状态值进行比较,并计算其方差,方差比较大的状态将获得接入网络的权限。其次,将具有媒质接入约束和随机短时延的网络控制系统建模为随着调度信号进行切换的切换系统。借助Lyapunov稳定性理论和线性矩阵不等式方法（ LMI ）进行了稳定性分析以及控制与调度的耦合设计。最后,对LSLS与控制的耦合设计方法进行了仿真验证,并与已有的最大误差优先-尝试一次丢弃（ MEF-TOD）调度与控制的耦合设计方法进行了比较。结果表明,LSLS与控制的耦合设计方法在控制性能上优于MEF-TOD调度与控制的耦合设计方法。

First, a new scheduling scheme called least-square-like scheduling （ LSLS ） scheme, which combines priority-based scheduling with communication sequence （ or scheduling sequence ） , was pro-posed. Measurements from sensors were sent to LSLS scheduler in each sampling period, and then the scheduler was compared with the measurements determined by the scheduling sequence of LSLS with the states of the ideal dynamics which are determined by the same sequence. The variances between actual states and ideal states were hence calculated. In this context, the states corresponding to the scheduling sequence of bigger variance gained the access to
