Robust Tracking Control of Robot Manipulators Using Only Joint Position Measurements

الملخص EN

This paper concerns the tracking control of a robot manipulator with unknown uncertainties and disturbances.

It presents a new control method that uses only joint position measurements to design a tracking controller.

The controller has two parts.

One is based on a feedback linearization technique; it makes the nominal model of a manipulator asymptotically track a desired trajectory.

The other is based on the idea of equivalent input disturbance (EID); it compensates for uncertainties and disturbances.

Together they enable a robot manipulator to precisely track the desired trajectory.

The new control algorithm is applied to a two-link robot manipulator, and simulation results demonstrate the validity of this method.
