摘 要: | 针对同时具有网络诱导时延与丢包的无线网络控制系统,研究了系统的建模与控制问题。考虑到系统随机时延可能大于一个采样周期且伴有连续丢包情况,结合基于事件驱动控制的思想建立了新的数学模型,并进一步给出了无线网络控制系统指数稳定的充分条件。最后用仿真实验验证了该方法的有效性。

Abstract: | In this paper,the system modeling problem and control problem for wireless networked control systems(WLNCS) with network-induce delay and data packet dropout are considered.Assumed that the random time-delay is more than one sampling period with continuous packet dropout,a linear system model based on event-based control theory is presented.Furthermore,a sufficient condition for the exponential stability of the closed-loop system is derived.Finally,simulation results show that the proposed method is effective. |
