Descrição
Resumo:[EN] The present work deals with the tracking problem of a mobile robot (3,0) based on the kinematic model and proposes a control strategy that takes into account a priori input signals bounds i.e. the linear and angular velocity of the robot. The objective of this control approach is to maximize the effectiveness of the actuators without taking a risk in the system stability. The resulting nonlinear control is composed of a nonlinear compensator based on the kinematic model and nested saturation approach. The control law can be tuned to force the error dynamics trajectories to enter in a neighborhood of the origin in a finite time and remain thereafter. Experimental results show the performance of the closed loop system. Furthermore, owing to simplicity, the proposed control law is suitable for application where on-board computational resources are limited.
