A position control approach for direct-drive robot manipulators with permanent magnet AC (PMAC) motors is proposed. The conventional vector control architecture has been simplified by specifying the motor stator phase so that the rotating d-axis current is zero. The position control is designed to be an enhanced fuzzy PD controller, by incorporating two nonlinear tracking differentiators into a conventional fuzzy PD controller. The proposed control methodology is easy to implement, and exhibits better control performance than conventional control methods. Experiments conducted on a single-link manipulator directly driven by a PMAC motor demonstrate the validity of the proposed approach.

Abstract Some industrial processes have nonlinearities and large delays. This causes instabilities and many difficulties for the system tuning. This paper presents tuning of a fuzzy PD controller for a nonlinear object with a large delay and an integrator in its structure. The simulation and respective results shows that the presented options assist for much better and easier system setup.
