摘要
研究具有时延和数据包丢失的多输入多输出网络控制系统的指数稳定性和控制器设计问题。对在传感器与控制器、控制器与执行器间皆有时延和数据包丢失的网络控制系统结构进行了简化,建立了动态输出反馈网络控制系统模型。基于异步动态系统理论、Lya-punov稳定性原理和线性矩阵不等式方法导出网络控制系统指数稳定的半负定矩阵条件和动态输出反馈控制律设计方法。数值算例说明结果是可行的。
The exponential stability and controller design problems of multi-input multi-output(MIMO) networked control systems( NC- S8) with time-delay and the data packet dropout are studied. The structure of NCS with data packet dropout and time-delay in sensor- controller and controller-actuator is simplified. A model for dynamical output feedback NCS is presented. Based on the asynchronous dynamical system theory, Lyapunov stable theory and linearity matrix inequalities, the negative semi-definite matrix condition of exponential stability and the controller design of NCS are educed. Numerical examples show that the results are feasible.
