The object of this paper is to give a g guide for designing the human-robot collaborative control system attaching importance to maneuverability of the operator. The operative “feel” is quantitatively evaluated using the norm of input-output signal obtained from the sensors during operation. As an example of the human-robot collaborative system, the subjective operative “feel” of the operator is qualitatively analyzed during the sine wave following task using 1-link operation arm. In addition, the control performance of the operator is examined from the viewpoint of H∞ control using the measurement data during the collaborative operation. As a result, it was suggested that the operator executes the given task while adequately reforming the sensitivity function and complementary sensitivity function of the closed loop system of the collaborative system. Use of this method enables design of the control system taking into consideration the operative “feel” of maneuverability.
