In order to cope with the inertia parameter uncertainty of a free-floating space robot system,an adaptive trajectory tracking control method is proposed in Cartesian space.Dynamic equations in the joint space of the free-floating space robot system are formulated using the extended manipulator model,and then the dynamic equations in Cartesian space of the free-floating space robot system are derived.During the design of the adaptive controller for the free-floating space robot based on inverse dynamics,a no...
