Abstract
A gimbal control method, a gimbal control system and a gimbal device are provided. The method includes steps of: obtaining simulation position information, measurement position information and simulation angular velocity information of a Pitch axis of a gimbal in real-time; calculating a first position error between the simulation position information of the Pitch axis and the measurement position information of the Pitch axis; processing the first position error with proportional-derivative calculation, wherein the first position error is compensated with the simulation angular velocity information during the proportional-derivative calculation; and, according to a result of the proportional-derivative calculation after compensating, generating a first torque control instruction for controlling a torque of a Pitch axis motor, so as to enable the Pitch axis to reach a position corresponding to the simulation position information of the Pitch axis. According to the present invention, a brush motor is adopted.
