摘要:
研究了同时存在数据传输延时与数据包丢失的网络控制系统的建模问题.系统中传感器采用时间驱动,执行器与控制器采用事件驱动,传感器的数据采用单包传输.假设传输延时小于采样周期,且数据包传输的成功率一定,则整个网络控制系统可以描述为一个具有2个事件的异步动态系统.针对对象状态均可测,控制律采用状态反馈的情况,利用双线性矩阵不等式方法,讨论了网络控制系统指数稳定的问题,给出了稳定性的充分条件.
Abstract:
Considering the network transfer delay and data packet dropout simultaneously in networked control systems, the modeling problem is discussed. The sensor node is time-driven, and sampled at fixed period. The executor and controller are event-driven. The sampled data are lumped together into one network packet and transmitted through the network. Assuming that the transfer delay is less than the sampling period, and data packets transfer successfully at a fixed rate, the networked control system is an asynchronous dynamical system with two events. Using the bilinear matrix inequality method, the system’s exponential stability is discussed with the status feedback control when the system state is acquirable.
