The present paper further enhances these results by providing a detailed model that captures time-varying delays, data dropouts and network capacity for wireless ring token networks. It also provides a new theorem showing how an asynchronous controller can be implemented, which maintains an l2-stable system. Simulations show that the asynchronous control of a passive motor reduces the overall distortion when compared with a synchronous controller which relies on lossy data reduction techniques. These two distinct results pave the way to study high-performance rate-adaptive control schemes that minimize their control rate in order to match the network capacity.</style></abstract></record></records></xml>
