ABSTRACT:
A position control circuit having a demodulator with automatic tuning capability for use in an electro-hydraulic positioning system used to position a servo device. The position control circuit includes the demodulator, an analog to digital converter with an input voltage range, and a microcontroller. The demodulator has a gain and is operable to convert a feedback signal from the servo device to a position signal having a lower voltage value when the servo device is at its 0% position and an upper voltage value when the servo device is at its 100% position; the lower voltage value and upper voltage values being a function of the demodulator gain. Upon operator initiation, the microcontroller automatically calculates the largest value for the demodulator gain that results in the position signal from the demodulator having a lower voltage value within a lower voltage range and an upper voltage value within an upper voltage range, where the lower voltage range and the upper voltage range are within the input voltage range of the analog to digital converter.
