“…To overcome the position tracking problem of a servomechanism composed of a PMSM and ball screw, Wang and Lin [19] developed a robust tracking control based on the principle of vector control of PMSMs and ball screw mechanics. Wang and Sun [20] developed a multiloop control system that combines the rudder position, speed, and torque control to improve the load‐torque performance of a PMSM on a rudder test bench by using sensor signal processing and control parameter tuning. Lee and Lee [21] developed a virtual feed‐drive system for five‐axis machine tools such that the influences of the motor driving control parameters on machining performance could be assessed easily without performing actual machining operations.…”

To achieve high‐speed and high‐accuracy positional motions in a permanent magnet synchronous motor (PMSM)‐driven servomechanism, this study developed an extended proportional–integral–proportional (PIP) control, particularly by considering the limitations of the hardware structure of commercialized PMSM drivers. PIP feedback and feedforward controls were developed, such that the existing PIP feedback control, which is extensively used in commercialized PMSM drivers, can perform dynamic and friction torque compensations in PMSMs. Thereafter, an extended PIP control with the newly added design degrees of freedom was developed based on the PIP feedback and feedforward control structures, thereby further improving the position response of the PMSM‐driven servomechanism and positional motion performance of advanced motion control systems. Position control experiments were performed on a commercialized PMSM pack installed on the rotary table of a five‐axis computer numerical control (CNC) machining center. Results indicate that the extended PIP control can significantly reduce position errors, which can be minimally influenced by the change in frequency of the position command. Furthermore, circular motion experiments were performed along the motion axes of the five‐axis CNC machining center. Results indicate that the extended PIP control with dynamic matching design can significantly reduce the root‐mean‐square value of contouring errors and roundness error value. Experimental results validate the feasibility of the extended PIP control for improving the positional motion performance of the PMSM‐driven servomechanism.
