Abstract

This paper presents a modelling and identication method for a wheeled mobile robot, including the actuator dynamics. Instead of the classic modelling approach, where the robot position coordinates (x; y) are utilized as state variables (resulting in a non linear model), the proposed discrete model is based on the travelled distance increment ∆ᶩ. Thus, the resulting model is linear and time invariant and it can be identied through classical methods such as Recursive Least Mean Squares. This approach has a problem: ∆ᶩ can not directly measured. In this paper, this problem is solved using an estimate ~∆Ɩ based on a second order curve approximation. Experimental data were colected and the proposed method was used to identify the model of a real robot.
