1. A work machine comprising:
a travel unit;
a swing unit provided on the travel unit swingably;
an angular velocity sensor that is attached to the swing unit and outputs an azimuthal angular velocity of the swing unit;
a measurement device that measures an azimuth of the swing unit; and
a controller that corrects the azimuthal angular velocity based on the azimuth measured by the measurement device and controls the swing unit based on the corrected azimuthal angular velocity.
