摘要
针对网络控制系统中存在的随机掉包和延迟情况,采用前向和反馈补偿设计网络状态观测器,并运用状态预估的方法设计网络预估控制系统(PNCS),作为网络控制系统中的掉包和延迟的整体解决方案.同时介绍PNCS系统各部分设计的方法,并给出了闭环系统的稳定性条件.最后通过一个仿真算例验证了该系统的有效性.
An integral solution, the predictive networked control system （PNCS）, is presented to eliminate the effect caused by the random networked-induced delays and data packets dropout, which adopts the system state prediction of model predictive control and the networked system state observer. The design method of all parts in PNCS is introduced, and the stability conditions of closed-loop system are analyzed. Finally, a simulation example shows its effectiveness.
