Abstract: Disclosed are a vehicle-mounted camera gimbal servo system and a control method. The vehicle-mounted camera gimbal servo system includes a camera tri-axial gimbal and a servo control apparatus. The camera tri-axial gimbal includes a pitch motor, a roll motor, a yaw motor, a roll arm (1), a pitch arm (4), a yaw arm (5), a gimbal top (7), a camera (11), a pitch-axis bearing (12), and a counterweight block (13); the pitch motor includes a pitch motor stator (2) and a pitch motor rotor (3); the yaw motor includes a yaw motor stator (6) and a yaw motor rotor (8); the roll motor includes a roll motor stator (9) and a roll motor rotor (10); the servo control apparatus includes an inertial measurement unit, a three-dimensional modeling control unit, an angular velocity loop control unit, and an angular displacement loop control unit.
