High-gain proportional-integral-derivative (PID) position control can achieve stiff position control but it involves the risk of overshoots in some cases such as discontinuous position commands and disturbances. This paper presents a new position controller that achieves accurate trajectory tracking and overdamped resuming motion from large positional errors and disturbances. The proposed controller is a combination of PDD2 (proportional, derivative, and second derivative) controller with nonlinear D2 term, which we call (N-PDD2), and the output of a friction compensator (FC). The nonlinear D2 term allows the use of high gain PDD2 and thus, advantageous in dealing with disturbances. Accurate trajectory-tracking is achieved due to friction compensation. The validity of the proposed controller was demonstrated through experiments in realizing overdamped motion and accurate tracking simultaneously and achieving improvement in robustness to disturbances in a robotic manipulator.
