Title:
SINGLE-ENCODER ACTUATOR FOR AIRCRAFT AND POWER-ON SELF-TEST METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/061016
Kind Code:
A1
Abstract:
Disclosed in the present invention are a single-encoder actuator for an aircraft and a power-on self-test method therefor. By means of a vector control algorithm, a controller controls a servo motor to rotate, and by means of a harmonic reducer, the motor drives a rudder arm to rotate. On the basis of the feature that the harmonic reducer has no backlash, and by finding an original point every time an actuator is powered on for stroke self-test, the position of the rudder arm of an output shaft can be calculated according to the recorded number of turns of a rotor and by reading the position of the rotor. Therefore, the cost and installation difficulty are reduced while the high-performance requirement is met.
