| 中文摘要 |
| 针对同时具有不确定短时延及数据包丢失的网络控制系统, 引入丢包补偿器补偿丢包对系统的影响, 当发生数据包丢失时, 控制器采用丢包补偿器产生的预估状态代替系统的真实状态计算控制量. 同时考虑不确定短时延的影响, 将网络控制系统建模为一类具有参数不确定的离散切换系统. 利用线性矩阵不等式(linear matrix inequality,简称LMI)方法给出了系统的保成本控制器和丢包补偿器的协同设计方法, 仿真结果表明所提出的方法是有效的. |
| 英文摘要 |
| For the networked control systems (NCS) with time-varying delay less than one sample period and data-packet dropout, a compensator is introduced to compensate the effect of data dropout. The controller will adopt the estimate state generated by the compensator to compute control variable if the sensor data is dropout in the current period. Considering the effect of uncertain short delay, the NCS is modeled as a discrete switched system with parametrical uncertainties. Based on this model.~a cooperative design approach of the controller and the compensator are given in terms of a group of linear matrix inequalities (LMIs). Finally, an example shows the effectiveness of the proposed approach. |
