Abstract :
Considering the multi-rate output for a single closed loop in Networked Multi-rate Control System (NMCS), interpolation and decimation method is employed to adjust control period such that control output can vary with available bandwidth on the background of the time varying network traffic. Based on augment state space, non-uniform multi-rate control model and pole assignment algorithm are shown in this paper. At last, simulation results were given to illustrate its validity.
