The friction is detrimental to the normal work of the servo system, but the friction mechanism is very complicated. In this paper, Tustin friction model is used as the friction parameter identification, reflecting the phenomenon of friction in the system, and laying the foundation for the friction compensation. Tustin model is a nonlinear friction one, and(More)
Wireless Personal Area Networks using UWB technologies have shown great potential as future home networks. In this paper we do some researches on the ARQ mechanism which provides the probability of involving the relay nodes into the UWB multi-hop wireless network. Based on the researches we design an ARQ mechanism combining Partial Window Multiple Rejects(More)
