The line-of-sight(LOS) stabilization system is a precision electro-mechanical gimbal assembly to isolate the load from its environmental and point the payload toward the target in a desired direction. Rejection disturbance is a major source of the LOS the stabilization control. This paper describes the design approach of disturbance rejection using sliding mode controller with disturbance observer and sliding mode observer. Simulation results show that the proposed approach is effective to reject disturbance and to improve stabilization performance.
