【摘要】 针对传感器为时钟驱动、执行器、控制器均为事件驱动的一类非线性网络控制系统(net- worked control systems,NCS),通过在信息接收端设置一定长度的缓存,可以将时变的网络诱导时延转化为固定时延,并且将此类NCS建模为一类具有输入-输出时延的非线性时延系统．基于建立的模型,利用Lyapunov定理和Razumikhin定理给出了系统渐近稳定的充分条件,同时给出使系统保持渐近稳定的最大允许网络诱导时延．最后通过算例验证了时延小于最大允许网络时延时,NCS是稳定的．更多还原

【Abstract】 Considering a class of nonlinear networked control systems with clock-driven sensor and event-driven controller and actuator, the time-vary network-induced delay is reshaped to deterministic delay by using queuing mechanisms. Then the networked control systems (NCS) is modeled as a nonlinear delay system with input delay. In terms of the NCS model, the sufficient condition for NCS stability is given by using Lyapunov theorem and Razumikhin theorem, and also the bound of network-induced delay is given. Finally, an example validates that the NCS is stable when the delay is within the maximum allowable delay.更多还原
