Abstract
A position control method for a servo, includes: receiving, from a control terminal, a motion control command that comprises a motion planning parameter about position of an output shaft of the servo; acquiring speed information or time information indicated by the motion planning parameter, and determining a constant parameter control duration according to the speed information or time information; determining a control parameter corresponding to a constant parameter control stage according to the constant parameter control duration and a preset constant parameter; performing a transient adjustment to the servo when the constant parameter control stage ends, and changing the control parameter to an adaptive operation parameter when the transient adjustment ends; and controlling a rotation angle of the output shaft of the servo to perform a position control of the servo, based on duration values and control parameters corresponding to each of a plurality of control stages.
