1. A landing gear system, comprising:
a casing configured to couple to a fuselage of an aircraft;
a steering rod comprising a first side inserted into the casing and a second side connected to a tire;
a magnetorheological (MR) damper, in the casing, that comprises a cylinder coupled to the casing and a piston coupled to the steering rod;
a sensor unit configured to acquire measurement data of a state of the aircraft; and
a controller configured to control, based on the measurement data, a damping force of the MR damper,
wherein the sensor unit comprises a first sensor for measuring a stroke of the MR damper and a second sensor for measuring an acceleration of the casing.
