大延时网络化控制系统保性能控制

Guaranteed cost control for networked control systems with large time delays

针对事件驱动方式下的大延时网络化控制系统控制性能下降的情况,建立了时钟驱动方式的网络化控制系统模型,提出了一种基于状态预估的保性能控制设计方法。基于李亚普诺夫稳定性理论,设计了大延时时钟驱动方式的保性能控制器,使得系统在大延时的情况下仍能保证稳定并具有一定的控制性能,仿真算例验证了这种控制器的可行性。

Time-driven system model was provided for descent performance of event-driven networked control systems with large time delays. An approach of guaranteed cost controller with preestimate state based on Lyapunov theory was raised, which can stabilize the systems with given control performance under larger time delays. Numerical example shows the feasibility of the proposed controllers design procedure.
