ABSTRACT:
A control system for a motor which drives a tape capstan includes a capacitor (91) which holds a sample of a ramp signal which is sampled and restarted in response to tachometer pulses. The output of an amplifier (90, 100) which amplifies the difference between the stored voltage and a reference is integrated by a passive integrator (106, 92) coupled to the capacitor (91). The arrangement provides prediction of change of a discontinuous speed signal and is useful for slow running motors of low inertia.
