    Abstract

    Many robot applications demand a robot to interact with an environment that is not exactly known beforehand. In these situations, the controller should be careful not to make the robot unstable, i.e. keep its kinetic energy bounded.
    One way to accomplish this is to use a form of impedance control (introduced by Hogan [1]): the control torques are taken equal to the gradient of an (artificial) potential field with the minimum at the desired position. Thus, the controller mimics a spring connected between the robot and the desired position. The kinetic energy of the robot is determined by the potential field, and if this field has a global minimum, the kinetic energy is bounded.
