| Abstract: | A class of networked predictive control algorithm based on multi-rate sampled system is proposed by lifting technique for the problems of network delay and package dropout and combining predictive controller with compensator of network delay. The results of computer simulations demonstrate that the network delay is compensated, performance requirement for NCS is optimized, network efficiency is improved, and the stability of networked closed-loop is guaranteed. |
