This paper presents an assist control method for a flexible parts conveyance task using a power assist conveyance system. The assist control method should be designed so as not only to suppress vibration but also to reduce the degradation of operating feel. For this purpose;
multiple impulse-shaped signals are used as feedforward signals in order to reduce the vibration of flexible parts during conveyance. In addition;
the adjustment time is introduced to adjust the input timing of the impulse-shaped signal and to suppress vibration. In order to improve the degradation of operating feel;
the smaller amplitudes of the three impulse-shaped signals are used and input repeatedly. The effectiveness of the proposed system was verified experimentally. © 2013 Wiley Periodicals;
