基于执行器部分失效的网络化控制系统完整性研究

摘要

The networked control system with Markov delays and parameters uncertainty is studied in this paper. A quasi T-S fuzzy model is employed to represent the system, based on Lyapunov functional, sufficient conditions for closed-loop of networked control system possessing asymptotically stable against actuator failure are given, and the corresponding design method of robust fault-tolerant controller is presented via solving several linear matrix inequalities. Finally, simulation proved the effectiveness of the de%针对一类具有马尔可夫特性时延的网络化控制系统,考虑系统参数不确定性的影响,基于时延T-S模糊模型建立数学模型,通过构造离散Lyapunov函数,推证出了确保网络化控制系统在执行器部分失效时具有鲁棒完整性的充分条件,并以求解LMIs给出容错控制器的设计方法.最后通过仿真验证了文中所述方法的可行性和有效性.
