Abstract
The present disclosure provides a control method for an electronically controlled servo mechanism as well as an apparatus and a robot thereof. The method is for an electronically controlled servo mechanism including a servo having a PI controller, which includes: obtaining related parameter(s) of the PI controller before tuning, where the related parameters includes a proportional coefficient and an integral coefficient; obtaining a current rotational angle of an output shaft of the servo, and calculating an angular deviation between the obtained current rotational angle and an expected rotational angle of an output shaft of the servo; and tuning the related parameter(s) of the PI controller based on the proportional coefficient, the integral coefficient, and the angular deviation. In such a manner, the parameter(s) of the PI controller are tuned to make it equivalent to a P controller, thereby avoiding the large oscillation caused by external interference.
