摘要
利用节点采用事件–时间驱动方式建立了变采样网络控制系统,在固定时延稳定控制的基础上,根据预测控制值和预测反馈值给出该系统在变时延下所对应的状态转移矩阵,研究了满足变采样网络控制系统稳定的预测误差和预测时间的条件,最后给出了一个例子说明分析的结果.
A variable-sampling-rate networked control system is developed by means of the event-time-nodes-driving. On the basis of the stable control with time-invariant network-delay, we use the predicted control value and the predicted feedback value to develop the state transfer matrix of the networked control system with time-varying network-delay. The prediction error bound and the conditions on the prediction time for ensuring the stability of the networked control systems with variable sampling-rate are studied. Finally, an example is given to illustrate the analysis results.
