Abstract: A steering control device for controlling drive of a motor that drives a steering mechanism according to an operation amount of a steering wheel, includes a first torque command controller that instructs the motor on motor torque according to the operation amount of the steering wheel, and a second torque command controller that instructs the motor on the motor torque according to the operation amount of the steering wheel in parallel with the first torque command controller. The second torque command controller suppresses a frequency region corresponding to disturbance added to the steering mechanism with respect to the operation amount of the steering wheel with a filter.

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.
