Abstract: A method for controlling an attitude of a payload includes determining an input torque based on an input angle and one or more motion characteristics of the payload, determining an estimated disturbance torque based on one or more motion characteristics of a carrier to which the payload is coupled, and calculating an output torque based on the input torque and the estimated disturbance torque. The output torque is configured to effect movement of the carrier to achieve a desired attitude of the payload.

Abstract: An apparatus includes a carrier, one or more first sensors, one or more second sensors, and one or more processors. The carrier includes a first frame and a second frame. A payload is affixed to the first frame. The second frame is rotatably coupled to a movable object. The one or more first sensors are disposed on the payload and configured to measure one or more motion characteristics of the payload. The one or more second sensors are disposed on the carrier and configured to measure one or more motion characteristics of the carrier. The one or more processors are configured to determine an input torque based on the one or more motion characteristics of the payload, determine an estimated disturbance torque based on the one or more motion characteristics of the carrier, and calculate an output torque based on the input torque and the estimated disturbance torque.

Abstract: Disclosed are angle sensing devices and gimbal platforms adopting the same. One angle sensing device disclosed herein comprises: a rear cover provided with an upper fitting face; a bracket provided with a lower fitting face, the lower and upper fitting faces being arranged to face each other and spaced apart from each other by a pre-set spacing; and a sensor mounting plate for mounting an angle sensor; wherein the sensor mounting plate is provided between the upper and lower fitting faces, and the pre-set spacing is greater than the thickness of the sensor mounting plate, such that the sensor mounting plate is movable between the upper and lower fitting faces.
