摘要：

针对网络控制系统(NCS)的随机短时延问题,在传感器和执行器由时间驱动、离散控制器由事件驱动方式下,将NCS描述为切换系统模型。结合极点配置和特征根连续变化原理,根据时延与增广矩阵特征根最大模长之间的关系,将切换系统进行简化并设计相应的状态反馈控制器。实验结果表明,该控制器求解简单、易于实现,且可根据实际系统性能要求选择控制参数。

Abstract:

To address the random short delay problem,this paper describes the Network Control System(NCS) as a switching system based on the combination of time-driven sensors and actuators and event-driven discrete controllers.By using the pole placement and the continuous change principle of the characteristic root,the switching system is simplified and the corresponding state-feedback controller is designed according to the relationship between delay and the maximum modulus length of the characteristic root of the augmented matrix.Experimental results show that the controller is simple and easy to implement,and can choose control parameters according to the actual system performance requirements.

Key words: Network Control System(NCS), random delay, switching system, pole placement, characteristic root
