查询词典 acceleration time

After a detailed analysis of the forces in subway train's running, the dynamics mathematical model of subway train is constructed; the eventbased control technology is adopted to solve the controlling of subway, the velocity and acceleration function with respect to the distance are deduced by introducing the action reference variable in the control problem which the object is to minimize the running time. The running scheme can be programmed in realtime, the delay caused by uncertain events is avoided. So it offers a new way for the metro research.
