Comparative Study of Three Different Path Tracking Controls in Mobile Robots. International Journal of Computer Applications. 74, 5 ( July 2013), 47-51. DOI=10.5120/12885-9823
This paper presents a comparative study of three different path tracking control laws for the formation of a group of nonholonomic mobile robots. By introducing a uni?ed error of the formation and trajectory tracking using; the dynamic feedback linearization control [1], dynamic-static feedback linearization control [2] and nonlinear time-invariant control [3] are compared. The simulations results show that the dynamic-static feedback linearization technique presents a stable tracking with smoother behaviour and avoiding discontinuities for tracking trajectory of the robot leader. Finally, this method was implemented experimentally in three different paths formatting a simple triangle with three mobile robots in a leader-follower type motion. Moreover, the analysis in this paper reveals some important issues raising that the following control on this system can be extended to underactuated AUVs in future work.
