Stabilization of uncertain systems subject to hard bounds on control with application to a robot manipulator

Abstract

The problem of estimating the region of stability for uncertain systems with bounded controllers and the sliding mode requirement is examined. A novel type of controller for a class of linear time-invariant systems subject to uncertainties is proposed. A transformation for decoupling the fast and slow states is utilized to investigate the stability-domain estimates of the system. The results are then applied to a two-joint planar manipulator and illustrated by computer simulation. >
