AI总结:

本文基于Lyapunov Krasovskii方法,通过线性矩阵不等式获得非线性网络控制系统的稳定性条件,并应用于两自由度机械臂系统,实现显著改进。

摘要:

本文考虑了一个非线性网络控制系统,其中控制器、传感器和执行器通过多个通信链路连接。在每个链路中,传输延迟、数据包丢失、采样抖动和数据包顺序错误等网络效应通过时变延迟捕捉。基于Lyapunov Krasovskii方法进行稳定性分析,以线性矩阵不等式形式获得非线性NCS的稳定性条件。结果应用于两自由度机械臂NCS,显示出与先前工作相比的显著改进。

英文摘要:

In this paper, we consider a nonlinear networked control system (NCS) in which controllers, sensors and actuators are connected via several communication links. In each link, networking effects such as the transmission delay, packet loss, sampling jitter and data packet miss-ordering are captured by time-varying delays. Stability analysis is carried out based on the Lyapunov Krasovskii method to obtain a condition for stability of the nonlinear NCS in the form of linear matrix inequality (LMI). The results are applied to a two degrees of freedom robot arm NCS which shows a considerable improvement with respect to the previous works.
