Abstract: The present disclosure provides a load stabilization device, a control method thereof, and a computer readable storage medium. In the load stabilization device, a motion sensor, a processor, a stabilization motor, and a parallelogram mechanism constitute a closed-loop feedback control system. A control instruction for the stabilization motor is generated based on a velocity of a second end of the parallelogram mechanism in a direction of gravity relative to a ground, where the second end may carry a load, and the stabilization motor is controlled to drive, according to the control instruction, the parallelogram mechanism to rotate relative to a base, so as to at least partially offset or compensate for jitter of the load carried at the second end of the parallelogram mechanism in the direction of gravity, suppress disturbance generated at a first end of the parallelogram mechanism, and stabilize the load carried at the second end.

Abstract: A gimbal control method includes configuring, while a gimbal is in a power-on state, turning-off motor control parameters according to a mass of a camera device carried by the gimbal. The gimbal includes an electric motor. The turning-off motor control parameters are configured to control the electric motor when the gimbal is powered off or enters a sleep state. The method further includes, in response to the gimbal being powered off or entering the sleep state, controlling a torque of the electric motor to decrease gradually from a starting moment at which the gimbal is powered off or enters the sleep state according to the turning-off motor control parameters.

Abstract: A control method for a non-orthogonal gimbal includes obtaining an actual attitude of the gimbal, determining a target attitude of the gimbal according to the actual attitude of the gimbal and an angle between a first rotation axis of a first drive motor and a second rotation axis of a second drive motor, determining an attitude error according to the actual attitude and the target attitude, and controlling one or more of a plurality of drive motors according to the attitude error to cause the gimbal to approach the target attitude. The gimbal includes the plurality of drive motors including the first drive motor, the second drive motor, and the third drive motor. The gimbal further includes a base, a first axis arm, a second axis arm, and a third axis arm.

Abstract: A method of obtaining a mechanical position of a motor for an ESC includes obtaining magnetic field strengths of two or more Hall sensors respectively and determining the mechanical position of the motor based on the magnetic field strengths of the two or more Hall sensors. The magnetic field strengths are obtained by measuring a magnetic leakage of two or more pairs of magnetic poles by the two or more Hall sensors. The motor includes two or more Hall sensors and two or more pairs of magnetic poles. The motor is connected to the ESC; a phase difference between the two or more Hall sensors is a preset angle; and arrangements between each pair of magnetic poles and the two or more Hall sensors are different.
