基于拟 T-S 模型的网络化控制系统鲁棒性分析
Robust analysis of networked control system using quasi T-S fuzzy model
摘要
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 （LMI） method, and the existing external disturbance input was considered and a feedback controller was designed. The inverted pendulum system was analyzed nu- merically. Results show that the system has a certain robust control law.关键词
