The embodiment of the invention discloses a jitter suppression method, a computer readable storage medium, a jitter suppression system, a vehicle and a device, relates to the technical field of motor control, and can improve the motor stability and reduce the calculation complexity of stable operation on motor jitter. The method comprises the steps of obtaining a jitter signal of the motor and/or equipment where the motor is located; and when it is judged that the jitter amplitude of the jitter signal is larger than the first threshold value, shock absorption operation is executed. The first threshold value is the amplitude of the equipment where the motor is located under the shaking condition. Motion parameters of the motor and corresponding preset values are obtained; the motion parameters represent attribute values of the motor in different states, and different motion parameters correspond to different preset values. And determining the magnitude of the target direct-axis current for adjusting and controlling the motor according to the magnitude relationship between the motion parameters and the corresponding preset values so as to slow down the jitter of the motor and the equipment where the motor is located.

    本申请实施例公开了抖动抑制方法、计算机可读存储介质、抖动抑制系统和车辆及装置,涉及电机控制技术领域,能够提高电机稳定性,且降低对电机抖动进行稳定操作的计算复杂度。所述方法包括获取电机和/或电机所在设备的抖动信号。判断在抖动信号的抖动振幅大于第一阈值的情况下,执行减震操作。第一阈值为电机所在设备抖动情况下的振幅。获取电机的运动参数及对应的预设值。运动参数表征电机的不同状态下的属性值,不同的运动参数对应不同的预设值。根据运动参数与对应的预设值的大小关系,确定调节控制电机的目标直轴电流的大小,以减缓电机和电机所在设备的抖动。
