Abstract
A signal representing the period between adjacent positive-going edges and the period between adjacent negative-going edges of a pulse train generated by a rotary encoder coupled coaxially to a motor is compared with a reference period signal for the motor to produce a deviation signal. The rotation of the motor is controlled by the deviation signal.
