Abstract :
We propose and validate algorithms for choosing finite word length priorities for dynamically scheduled networked control systems. Two schemes for selecting priority levels are studied, the first with a fixed arbitrary grid and the second with an auto-scaling grid. We prove that the system is uniformly and ultimately bounded in the case of the static encoding, and asymptotically stable with the auto-scaling methodology. Simulations of an inverted pendulum controller using these schemes are compared against a controller with point-to-point wiring
