A Bandwidth Allocation Strategy Based on the Proportion of Measurement Error in Networked Control System

Considering bandwidth limitation of networked control system (NCS), the performance of control system must be guaranteed and the bandwidth resources should be rational utilization. In order to realize the co-design of control and scheduling in networked control system, a proportion type of bandwidth allocation strategy is proposed in this paper. The remote controller which contains a QoS regulator is employed to allocate the bandwidth dynamically in a rational proportion by the measurement errors of each control loop. At last, a simulation is given which shows the feasibility of this strategy.
