Path tracking control for Dubin's cars
Proceedings of IEEE International Conference on Robotics and Automation, 2002The problem of driving a Dubin's car (1957) along a given path is considered. In order to model a realistic road-following problem, the car is supposed to move forward only and to have bounds on the turning radius (Dubin's car). We propose a discontinuous control scheme on the angular velocity of the vehicle, based on the theory of sliding modes, that ...

Path Tracking for the Dissipative Chaplygin Sleigh
2020 American Control Conference (ACC), 2020In this paper we study the problem of path tracking for the Chaplygin sleigh, a well known nonholonomic system. The dynamics and control of a Chaplygin sleigh with dissipation has received much attention in recent years, more so in light of the similarity of its dynamics to that of fish-like swimming. Recent work has shown the existence of limit cycles

Optimal Path Tracking With Dubins’ Vehicles
IEEE Systems Journal, 2021In this article, patrolling with Dubins’ vehicles is investigated. The vehicles have significant kinematic constraints such as minimum-turning radius, and are unable to move in a reverse direction, i.e., they can only track planar curvature-bounded paths.

Explicit Path Tracking by Autonomous Vehicles
Robotica, 1992SUMMARYWe have suggested a novel approach to autonomously navigate a full sized autonomous vehicle that separately treats vehicle control and obstacle detection. In this paper we discuss the vehicle control that has enabled our autonomous vehicle to travel at speeds upto 20mph.

Constrained Path Tracking at Varying Angles in a Mouse Tracking Task
Human Factors: The Journal of the Human Factors and Ergonomics Society, 2011Objective: This study was aimed to determine the effects of direction and path length on movement time when traversing a constrained path of width, W, in a mouse tracking task. Background: Tracking within constrained paths has been demonstrated to hold in many applications.

Path Generation and Tracking in 3-D for UAVs
IEEE Transactions on Control Systems Technology, 2009In this brief, we consider the problem of 3-D path generation and tracking for unmanned air vehicles (UAVs). The proposed path generation algorithm allows us to find a path satisfying arbitrary initial and final conditions, specified in terms of position and velocity. Our method assumes that aircraft structural and dynamic limitations can be translated

Path Tracking by the Nonholonomic Mobile Manipulator
2019 12th International Workshop on Robot Motion and Control (RoMoCo), 2019Following paper present a description of a non-holonomic mobile manipulator relative to three-dimensional path. Path has been orthogonally parametrized to the Serret-Frenet frame moving along the curve. Control law for the RTR manipulator with fixed first joint, mounted on the unicycle platform, which realizes the path following has been presented ...

Controller-Aware Path optimization for Enhancing Path Tracking Performance
2020 IEEE 23rd International Conference on Intelligent Transportation Systems (ITSC), 2020In a typical hierarchical autonomous driving framework, the motion planner and controller are developed separately for convenience. In most cases, the planner does not have knowledge of the controller tracking behavior, which leads to prediction error of the planning system when computing a reference path.
