Abstract
For the trajectory following problem of a robot manipulator, the standard computed torque control law is shown to be robust with respect to unknown dynamics by judiciously choosing the feedback gains and the estimates of the nonlinear dynamics. The choices for the constant gains depend only on the coefficients of a polynomial bound of the unknown dynamics. The asymptotic stability of the position and velocity tracking errors is also investigated. © 1991.
