摘要:

针对一类具有扰动的线性时不变网络控制系统中的网络诱导时延问题,设计了具有指数趋近律的滑模变结构控制器 ,并通过Lyapunov稳定性理论给出了具有扰动及时延的闭环网络控制系统的稳定性定理,最后通过仿真验证了此方法的鲁棒性、有效性。

Abstract:

Considering a class of linear time invariant networked control systems (NCS) with disturbance and time delay, a variable structure controller with exponential approach law was designed. The stability of the closed-loop NCS with disturbance and time delay was effectively guaranteed by Lyapunov stability theory. Finally, simulation results validated its robustness and effectiveness.
