Abstract :
Networked motion control system was a system with the limit of network bandwidth and deadline. Its performance not only depended on the design of control algorithm but also on the message scheduling. Because the mathematical optimization method was difficult to use online, this paper proposes a dynamic bandwidth allocation method based on actual system performance. Then according to the bandwidth, the sampling period is recomputed and the performance is optimized.
