MOTOR VELOCITY CONTROL WITHIN AN AIRCRAFT HYDRAULIC SYSTEM

摘要

A system comprises an aircraft hydraulic system motor, a position sensor, and a programmable controller. The aircraft hydraulic system motor includes a rotor whose position is detected by the position sensor. The position sensor produces an output representative of that position. The programmable controller is configured to receive the output of the position sensor and calculate an estimated velocity of the aircraft hydraulic system motor based on the output of the position sensor. The calculation of the estimated velocity comprises determining both a high bandwidth velocity estimation and a low bandwidth velocity estimation. The programmable controller is additionally configured to compare the estimated velocity to a desired velocity and direct the aircraft hydraulic system motor to increase or decrease velocity based on the comparison.
