Abstract

In the coordinated motion of cooperative multimanipulator carrying an object, the actuators must generate motion inducing forces and internal forces (grasping forces). When the desired motion inducing force and the internal force are completely resolved then the position control and the force control can be realized independently. Otherwise, conflicting motions may occur. This paper proposes a hybrid position/force cooperative control scheme based on workspace disturbance observer which realizes a robust motion control system. The conflicting motion can be avoided because the disturbance observer based position and force control are allowed to operate in the opposite direction to each other. The use of disturbance observer is also to make the system parameter relatively fixed to some value such that a fixed gain controller can be chosen to achieve the desired system performance. Finally, simulation results show the validity of the proposed hybrid position/force cooperative control of multimanipulator.
