An adaptive output feedback tracking control of robot manipulator via fuzzy logic based compensation

Abstract

In this study, we consider the output feedback position tracking control of robot manipulator via a fuzzy logic adaptation compensation method which enables the use of adaptive controller techniques for the full order but not fully linearly parameterized (LP) robot dynamics. Specifically we propose an output feedback position tracking controller that achieves semi-globally ultimately bounded link position tracking despite the lack of link velocity measurements and the non-LP uncertainties associated with the robot dynamics. Simulation results are presented to illustrate the performance of the controller.
