The invention relates to a control method for a magneto-rheological shimmy damper of an aircraft landing gear. The control method comprises the steps that the aircraft height, the aircraft flight speed, the aircraft flight deceleration and the aircraft descent speed are obtained; when the aircraft height is lower than a first height threshold value and higher than a second height threshold value,the initial working current of a coil of the magneto-rheological shimmy damper is obtained according to the aircraft flight speed, the aircraft flight deceleration and the aircraft descent speed; whenthe height of the aircraft is lower than a second height threshold value, acquiring an aircraft taxiing speed, an aircraft wheel swing angle, an aircraft wheel swing angle speed and an aircraft wheelswing angle acceleration; and the initial working current is adjusted according to the airplane taxiing speed, the airplane wheel swing angle, the airplane wheel swing angle speed and the airplane wheel swing angle acceleration, and a final working current value is obtained. Firstly, the control process of the control method is simple and free of cumbersome, the control reliability is further improved, the working current of the magneto-rheological shimmy damper coil can be accurately controlled, and the damping of the magneto-rheological shimmy damper can meet the requirement.
