US 2018/0188707 A1 · CRITICAL POINT LOCKING METHODS OF SERVOS AND DEVICES THEREOF

Abstract

The present disclosure relates to a critical point locking method of servos, including: computing a current target deviation according to a target position and an actual position, computing a variation value according to the current target deviation and a previous target deviation, determining whether the variation value being greater than a constraint value, modifying the current target deviation according to the current target deviation and a predetermined value upon determining the predetermined condition being satisfied, configuring the modified current target deviation as a current controlling deviation, and driving the servo to move toward the target position according the current controlling deviation. As such, the servo may lock the position for 360 degrees, the locking stroke of the servo may be improved, and the application of the servo may be enlarged.
