The invention discloses a two-degree-of-freedom micro-motion seat motion control method and belongs to the flight simulation field. A motion controller acts as a motion pose algorithm for analysis andlogic control, attitude motion simulation is performed through controlling two servo motors for driving an electric cylinder actuator, and the two servo motors are respectively used for driving a seat to make rolling and pitching motions. The method is advantaged in that the high-speed motion controller is utilized as the motion pose algorithm for analysis and logic control, attitude, speed and somatosensory motion response can be rapidly performed through controlling the two servo motors for driving the electric cylinder actuator, the vibration bump of a simulator at the low speed can be fully simulated, the motion seat can do attitude simulation for +/-16 DEG rolling and +/-16 DEG pitching in the maximum motion range and 96 DEG/s rolling and 113/s DEG pitching in the maximum attitude response speed, near-zero delay somatosensory operation can be achieved through external view frames plus motion seat attitude simulation, and simulation is made to be more realistic.
