针对存在量化的网络控制系统,提出了一种基于事件触发机制的预测控制设计方法,其中,信号从传感器传送到控制器和从控制器传送到执行器时需要被量化。建立了带有事件发生器的网络化模型,设计了事件触发机制,给出了预测控制律的设计方法,分析了闭环系统稳定性条件。最后,通过数值仿真验证了本文方法的有效性。
This paper investigates the design problem of the event-triggered model predictive control for networked control system(NCS),in which the signals will be quantized when transmitted from the sensor to controller and controller to actuator.The networked model with event generator is established and the event-triggered scheme is designed.And then,a model predictive control method is presented.The stability condition for closed-loop system is derived.Finally,a numerical simulation is given to illustrate the effectiveness of the proposed scheme.
