| 摘 要： | 在传感器、控制器和执行器均工作于时间驱动的工作模式下,综合考虑网络化控制系统(NCS)出现时延和丢包问题,提出一种拟T-S模糊模型.以时延和丢包出现的概率作为隶属度,根据丢包出现在系统中的不同环节,分别构造相应的系统模型,并利用线性矩阵不等式(LMI)方法证明系统的稳定性.在系统存在外部扰动输入的情况下,构造相应的反馈控制器,并通过对一个二阶倒立摆系统的数值分析证明系统具有一定的鲁棒控制律.

| Abstract: | Considering time-delay and data packet dropouts problem of networked control system(NCS),Quasi T-S fuzzy model was put forward,which was suitable for the systems that sensors,controllers and actuators work on time driven mode.Regarding the probability of the time-delay and data packet dropout as membership,according to the data packet dropout appeared in different node of system,the corresponding system models were constructed respectively.The system stability was verified by the linear matrix inequality(LM... |
