Title: Controller for railway train
Inventor: NARITA HIROSHI
IPC: B60L15/20
Filed: 1983-10-21
Abstract: PURPOSE:To enable to obtain the maximum adhesion tensile force when wheels race or slide by controlling the drive force of a train so that the rate of change of the adhesion coefficient between a rail and the drive wheel obtained from the drive force of the train and the peripheral speed of the wheel with respect to the slip speed becomes zero. CONSTITUTION:The maximum adhesion coefficient calculator muMC calculates an adhesion coefficient (mu) from a wheel drive torque Tm calculated on the basis of a motor current IM and a wheel peripheral speed VM. Then, a slip speed Vs is obtained from the speed VM and a train speed V, and the rate of change of the coefficient (mu) with respect to the slip speed Vs is calculated from the coefficient (mu) and the speed Vs. This change rate signal is integrated by an integrator to become a current command IMP2, which is added to a current command IMP1. A comparator outputs as a current command IMP the smaller one of the sum of the IMP1 and the IMP2 and the current limiter command.
