running variable
1.An admission control scheme with priority for real-time traffic was designed, and a discrete time queue model Geo1 + Geo2/Geo1,Geo2/s,s(PP) was proposed to investigate the performance of the multi-traffic admission control scheme,which based on the wireless communication running mechanism and the variable QoS(quality of service) re- quirement of multi-traffic.
5.The mathematic model of electric vehicle(EV) driven by permanent magnet synchronous motor (PMSM) is established, on the basis of which, the performance simulation of developing EV is done including the acceleration, speed-variable running and so on.
