Online Learning of Virtual Impedance Parameters in Non-Contact Impedance Control Using Neural Networks [PDF]

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2004
Impedance control is one of the most effective methods for controlling the interaction between a manipulator and a task environment. In conventional impedance control methods, however, the manipulator cannot be controlled until the end-effector contacts task environments. A noncontact impedance control method has been proposed to resolve such a problem.
