The invention discloses a frame type three degree-of-freedom cradle head
control system and a control method thereof. The frame type three degree-of-freedom cradle head
control system comprises an outer frame, a middle frame, an inner frame, a motor used for controlling the frames, reducing gearings and a sensor module used for detecting the position and the speed. The frame type three degree-of-freedom cradle head
control system is characterized in that the fine direction tuning and the pitching control of the cradle head are directly driven by adopting a
rare earth permanent magnet direct current torque motor. The outer frame adopts a common
direct current motor and a pair of reducing gearings to realize the coarse tuning of the direction, the structure of the middle frame is directly driven by the
rare earth permanent magnet direct current torque motor so as to realize the pitching
motion control a shooting device, and the structure of the inner frame is directly driven by the
rare earth permanent magnet direct current torque motor so as to realize the fine direction tuning of the shooting device. The invention further provides a control method of the frame type three degree-of-freedom cradle head control
system. The frame type three degree-of-freedom cradle head control
system disclosed by the invention has the advantages of large
mechanical strength, favorable vibration resisting performance, favorable image stabilizing performance, simple structure and light weight, and is suitable for
aviation shooting and multiple
aviation applications.
