Trajectory-tracking controller design with constraints in the control signals: a case study in mobile robots

Abstract

This paper is a continuation of a previous work of the authors, Scaglia et al., 1. A method is presented to choose the controller parameters such that, the values of the control actions do not exceed the maximum allowable and the tracking errors tend to zero. In addition, the analysis of the controller design parameters is included. The experimental results (laboratory experiments and a real world application) demonstrate the efficiency of the controller.
