An Automaton and Super-Twisting Sliding-Mode Control for Wall Following
Edgar Martínez, Rafael Murrieta-Cid, Héctor Hernán González Becerra · Journal of Control Engineering and Applied Informatics · 2023
This work proposes an approach for wall following with a differential drive robot in a polygonal environment using laser range finder measurements.We propose an automaton which manages the robot observationsand selects the control set-points according to the state in theautomaton. We also propose a super-twisting sliding-mode control whichrapidly reaches the control set-points.The approach allows the robot to continuously move without the need ofstopping when obstacles get in the path of the robot. Thisapproach allows the robot to following the walls fast and robustly.The wall following capability can be used to explore an unknown environment orto find objects in the environment.
