DIGITAL SMART SERVO CONTROLLER FOR SAFETY CRITICAL VEHICLE CONTROL

摘要

A smart servo controller that is operable to control a redundant configuration of servo motors corresponding to mechanical control surfaces of an aerial vehicle is described. The controller (i) outputs the necessary electrical signals that control the servo motors corresponding to each control surface, (ii) monitors those signals, (iii) monitors the positions of the servo motor shafts, and (iv) provides notification to a flight control computer upon detecting a servo malfunction.
