Abstract
A method of detecting a sensed parameter for a motor control system comprising: receiving a sensor signal, the sensor signal exhibiting a frequency responsive to an inductance of a non-contacting variable reluctance rotational displacement sensor, wherein the inductance is indicative of a displacement of the sensor and responsive to the sensed parameter; capturing a first transition of the sensor signal and a time associated therewith; capturing a second transition of the sensor signal and a time associated therewith; calculating a period for the sensor signal; and computing a value for the sensed parameter, the value responsive to the period.
