摘要
针对一类具有时变时延和丢包的网络化控制系统,研究执行器或传感器失效时系统的完整性设计问题.将丢包当作一种特殊时延,考虑综合时延的快变性,通过构造适当的Lyapunov-Krasovskii泛函,给出使闭环系统对执行器或传感器失效故障具有完整性的时滞依赖充分条件,并以求解LMIs的方式给出控制器的设计方法.以一个仿真算例验证了该方法的可行性和有效性.
Aimed at a class of networked control system with time-varying delay and data-packet-dropout,an integrality design was investigated against actuator and sensor failures.Taking the packet-dropout as a special kind of delay and the fast-varying characteristic of integrative delay into account,and by constrcturing an appropriate Lyapunov-Krasovakii functional,the delay dependent integrality sufficient conditions were given for a closed-loop system in the case of actuator and sensor failures.Then the controller was designed by means of solving several linear matrix inequalities.Finally,an example was given illustrate the effectiveness and feasibility of the proposed approach.
