Abstract
This paper proposes a new disturbance observer(DOB). The purpose of the DOB is to realize the plant performing like a model in the presence of disturbances which come from external environment and inherent nonlinearities and uncertainties in the plant. It is shown that the proposed DOB compensates those disturbances, nonlinearities and uncertainties, effectively. And it is theoretically proved that the proposed DOB can be guaranteed its stability for the stable plant. Its availability is shown by applying the DOB to the stabilization platform for EOTS(Electro Optical Tracking System).
