| 中文摘要 |
| 针对一类具有通信约束的随机时延网络控制系统, 提出一种基于试一次丢弃(try-once-discard, TOD)动态调度策略与鲁棒H∞控制器协同设计的方法. 考虑通信约束和随机时延的影响, 将系统建模为一类具有参数不确定性的离散切换系统, 并采用切换系统和Lyapunov稳定性理论, 给出了TOD调度策略下使闭环系统渐近稳定的鲁棒H∞控制器设计方法. 最后通过仿真验证了方法的有效性. |
| 英文摘要 |
| A coordinate design scheme of the try-once-discard (TOD) dynamic scheduling strategy and the robust Hinfinity controller for a class of networked control systems with communication constraints and random time-delay is proposed. Considering communication constraints and the random time-delay, we model the networked control system (NCS) as a discrete-time switched system with parameter uncertainties. Using the Lyapunov function and switched system theory, we develop the design procedure for the robust H-infinity controller under TOD scheduling strategy to maintain the asymptotic stability of the closed-loop system. A simulation example demonstrates the efficiency of the proposed method. |
