The inner current loop of commercial Permanent Magnet AC (PMAC) motor control systems ensures that motor currents follow the desired input commands and thus plays a central role in achievement of high-accuracy trajectory following. In this paper, we present a discrete-time approach to inner current loop control design. The inner loop control gains are determined based on a dynamic model-based calculation methodology. Experimental evaluation conducted on a commercial motion control system demonstrates the validity of the proposed approach.
