Digital motor speed controller

摘要

A switching circuit turns on at the beginning of a first clock signal and turns off in response to a gyroscope shaft detector signal. During the time the switching circuit remains on, a counter counts the cycles of a second clock signal. This resultant count is employed as an error signal for adjusting the output frequency of a pulse generator which is connected to a gyroscope motor. A feedback loop is created between the aforementioned components for achieving a preselected constant gyroscope motor speed.
