摘要
在同时考虑网络时延和数据包丢失的基础上,研究了网络控制系统的反馈控制器设计问题;用迭代的方法分析了数据包的丢失问题。在当前的状态测量不能被控制器实时得到时,利用旧的信息来控制系统,将网络化控制系统建模为切换模型。基于切换系统理论和分段Lyapunov函数理论,构造了线性矩阵不等式,推导出网络控制系统反馈控制器稳定的充要条件。数值仿真算例说明了所提方法的可行性和有效性。
The feedback controller is designed for network control systems with simultaneously time-delay and data packet dropout.An iterative approach is proposed to analyze the dropout of data packet.The controller makes use of the old information to control the system when the current state measurement can not be obtained by the controller instantly,and network control systems are modeled to switched models.Sufficient conditions of the stabilization of feedback controller of NCSs are presented based on piecewise Ly...
