抄録

The high readhesive characteristices of A. C. locomotives with rectifier and no Automatic Current Regulation was explained by N. Irie and K. Kuyama using one-axel slip model by introducing mechanical time constant_??_m, electric time constant τe and two grades (tractive effort/velocity, dynamic friction force/slip velocity). However almost all electric locomotives and multiple units with chopper control or three-phase traction have a strong ACR i.e. automatic torque regulator which promotes slip of the wheel that makes anti-slip control necessary.<br>To apply anti-slip control for such type of electric motor vehicles, we analized a Slip Velocity Feedback Torque Control and succeeded in deducing the same slip equation as that of A. C. locomotives with rectifier and no ACR by introducing two control parameters (electric time constant τe and feedback gain K) and then clarified the relations between the control parameters and slip-readhesion modes. Thus we find it easy to get better readhesive characteristics than those of A. C. locomotives with rectifier and no ACR by selecting the control parameters appropriately.
