Abstract:
An electric rolling stock control device includes a voltage controlling unit for controlling an output voltage of an inverter and a speed estimating unit for calculating a rotation speed estimation value of an electric motor. The speed estimating unit includes an initial speed estimating unit for outputting an initial speed estimation value, a steady speed estimating unit for outputting a steady speed estimation value, a correction coefficient calculating unit for calculating a correction coefficient based on the steady speed estimation value and a backup speed, and a correction speed calculating unit for storing the correction coefficient in a storage unit and calculating a correction speed by multiplying the correction coefficient by the backup speed.

Claim (Index 4):
The electric rolling stock controller according to  claim 1 , wherein\n in a case where the power converter stops an operation by an operation command during the calculation of the correction coefficient, the correction speed calculator calculates the correction speed by using the correction coefficient obtained by the previous calculation and stored in the memory.
