Abstract
The present disclosure relates to servo control technology, which provides a method, device, and terminal device for servo movement smoothing. The method includes: obtaining a starting position and a control command for a rotation of an output shaft the servo; determining an ending position and a rotation time for the rotation of the output shaft in accordance with the control command; constructing a movement curve of the output shaft based on the starting position, the ending position, and the rotation time; and controlling the output shaft to rotate from the starting position to the ending position in accordance with the movement curve. The above-mentioned method smooths the movement of the servo by constructing a simple linear function, which greatly reduces the calculation amount in comparison with the technical solution using the cubic Bessel formula, and is capable of reducing the requirements for the hardware performance of servos.
