基于存在时延和丢包的网络传输环境,针对具有参数不确定性的网络化控制系统,研究了其在传感器故障条件下的保性能可靠控制问题.根据Lyapunov稳定性理论和线性矩阵不等式(LMIs)方法,推导出使闭环网络控制系统在传感器故障条件下渐近稳定且保证综合性能指标满足要求的充分条件,并利用LMIs提出了保性能可靠控制率的设计方法.该控制算法在提高网络化控制系统可靠性的同时有利于系统综合体性能的优化.数值仿真验证了该方法的可行性和有效性.
Based on the network transmission environment with delay and packet loss, aiming at the networked control system with parameter uncertainty, the guaranteed reliability of the networked control system with sensor failure is studied. According to the Lyapunov stability theory and the linear matrix inequalities (LMIs) ) Method, the sufficient conditions for the closed-loop network control system to be asymptotically stable under the sensor fault condition and to ensure that the comprehensive performance index meets the requirements are derived. The LMIs are also presented to design a guaranteed guaranteed guaranteed rate of guaranteed performance. Control system reliability is also beneficial to the system performance optimization. Numerical simulation shows that the method is feasible and effective.
