The invention provides an active damping control method for a cylindrical linear actuator of a vehicle suspension, and belongs to the field of vehicle damping, linear motor control, power electronics and electric dragging. The method improves the active damping capacity of the vehicle. According to the technical scheme, the method comprises the following steps that a cylindrical linear actuator is installed on an automobile chassis and used for active damping of an automobile under the complex road condition; establishing a mathematical model of the cylindrical linear actuator; according to an integral sliding mode principle, a position loop controller, a speed loop controller, a q-axis current loop controller and a d-axis current loop controller of the cylindrical linear actuator are respectively established; a cylindrical linear actuator disturbance observer is established, and external force interference caused by complex road conditions is compensated in real time. The damping effect of the vehicle can be improved, the impact of complex road conditions on the vehicle is reduced, and the riding comfort is improved.
