Abstract
PURPOSE: To suppress racing and gliding by a method wherein a time delay circuit is provided in a revolution speed feedback circuit whose time constant is roughly same as the vehicle acceleration rate.
CONSTITUTION: A revolution speed feedback signal 108 obtained via a F/V converter 12 is inputted into a time delay circuit 13 whose time constant is approximately equivalent to that of acceleration that is an indispensible factor in terms of vehicle performance. A voltage controlling oscillator 10 transmits into a wave form generating circuit 11 a frequency signal 110 corresponding to the sum of a slide frequency command signal 109 corresponding to a torque command signal 101 and the output 112 of the time delay circuit 13. A current controlling amplifier 3 yields a deviation signal 103 formed out of a current command 102 answering a torque command signal 101 and a current feedback signal 106. A modulator 4, receiving an output signal 103 of the current controlling amplifier 3 and an output signal of the wave form generating circuit 11, yields a control signal 104 for a thyristor inverter 5.
