PROBLEM TO BE SOLVED: To provide an idling re-adhesion controller for electric rolling stock, which can attain optimum controlling condition as idling re-adhesion control. SOLUTION: Acceleration variationsΔα1 toΔα4 and velocity errorsΔV1 toΔV4 are calculated from respective shaft speeds fm1 to fm4 with an idling detection part 9. Factors g1 to g4 which indicate adhesive conditions based on the acceleration variationsΔα1 toΔα4 and the velocity errorsΔV1 toΔV4 are estimated by adhesive condition estimation parts 10 to 13. Based on the factors g1 to g4 and a current command value Ir at non-idling, a current command level Ia is determined by a current command level setting part 14. Since the current command level Ia is inputted into a primary lag system 16 so as to obtain an output current command value Ip during idling re-adhesion control, the retention time of the output current command value Ip during the idling re-adhesion control condition becomes zero, so that the variation range of the output current command value Ip also becomes small. |
