Abstract :
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.
