A disturbance suppression system based on frequency adaptive observation comprises an inertial reference unit base and a platform, a laser and a sensing device are arranged on the platform, the laser emits laser when first motion occurs to measure a first rotation angle, and the sensing device measures a first angular velocity; the control unit obtains a first target angular velocity according to the first rotation angle and the target rotation angle; the disturbance observation unit comprises a first observer which obtains a first observation frequency according to the first angular velocity and the first driving voltage; the second observer generates a first observation angular velocity according to the first angular velocity and the first driving voltage, the control unit generates a first angular velocity difference according to the first observation angular velocity and a first target angular velocity, and the second observer generates a first compensation angular velocity according to the first angular
