Implementation of a DSP-based, acceleration feedback robot controller: practical issues and design limits

The authors present the practical issues and design limits found by rigorous implementation of acceleration feedback in a DSP (digital signal processor)-based controller for a 5-axis industrial robot. They identify and quantify the effects of the feedback transducer and their interfaces in implementing acceleration feedback as part of a digital motion controller. Extensive experimental results document the performance issues which are fundamental to proper application of acceleration feedback in robot motion control.<
