TLDR
Simulation results show that the feedback gain of wheel velocity control can be high enough to suppress the serious skid, if the actuator delay is small enough.Abstract:
Motor's fast torque response is one of the advantages of electric vehicles (EVs), and the advanced anti-skid control is included in this advantage. Simulation results show that the feedback gain of wheel velocity control can be high enough to suppress the serious skid, if the actuator delay is small enough. The dynamics of wheel can be changed with this control, and the driven wheel's inertia can be increased accordingly. Experiments results showed the effectiveness of this skid prevention method. This is the fast minor loop control of driven wheel, achieved only with the fast torque response of the electric motor. Thus the method can be used to maximize the advantage of EVs.read more
