Modeling and path tracking control of a tracked mobile robot
2018 IEEE 14th International Colloquium on Signal Processing & Its Applications (CSPA), 2018This paper presents the modeling of 3DOF tracked mobile robot. It includes tracked speed, dynamics and kinematics of skid-steering mechanism. All the mathematical equations was derived and the modeling is developed in MATLAB Simulink software. Proportional-Integral-Derivative (PID) controller is used to control the tracked mobile robot speed.

Path Tracking and Control for Parallel Parking
2020 International Conference on Image Processing and Robotics (ICIP), 2020This paper demonstrates path planning and motion control for an automated parallel parking. The ultrasonic sensor based parallel parking control algorithm provides parking assist to ease the effort of driver. The trajectory for parking maneuver is generated based on the path planning algorithm to assist vehicle in the identified space with single ...

IRE Transactions on Automatic Control, 1959
Problems and possible methods of controlling the path of a vehicle in free space are discussed. Difficulties in determining and relaying the vehicle's position are given particular attention. There are no plans for publishing this discussion.

Path Tracking Control of Micro-Tracked Mobile Robot
Applied Mechanics and Materials, 2014The positioning accuracy of tracked mobile robot is low because of sliding in steering process. Taking the micro-tracked mobile robot as the platform, the interface force between tracks and ground was analyzed, and the motor model, kinematic model and dynamic model were established further.

A minimalist feedback control for path tracking in Cartesian Space
2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009The article proposes a new feedback control model that allows to track a generic curve in the Cartesian Space expressed through its implicit equation, and has minimal requirements in terms of measurement and computation capabilities. The model measures only the distance between the vehicle and the path, whereas it ignores the vehicle's orientation.

Path Tracking Control Problem Formulation of an LHD Loader
The International Journal of Robotics Research, 1998Load-haul-dump units (LHD) are loader-type vehicles that arefre quently employed in the underground mines for transfer of ore from the loading point to ore pass. Because they have to travel in the relatively narrow and restricted underground galleries, they have less height and are narrower than the ordinary mechanical loaders that are used in ...

A Control Approach for the Path Tracking of an AMR
IFAC Proceedings Volumes, 2001Abstract In this paper, the control algorithm for an AMR is studied and applied to a two-wheel drive AMR. The kinematic model of the AMR was reformed around its body center through a relative velocity relationship to controllability, which derives from the nonholonomic characteristics.

Path Tracking Controllers for Fast Skidding Rover
2016This article presents a comparative analysis between two new path tracking controllers, a linear and non-linear one. First, dynamic model of the vehicle moving on a horizontal plane is developed and validated with the experimental platform Spido. Then, to reduce the complexity, the model is linearized by assuming that the side slip angles remain small ...

A backstepping controller for path‐tracking of an underactuated autonomous airship
International Journal of Robust and Nonlinear Control, 2008AbstractIn this paper we propose a nonlinear control approach for the path‐tracking of an autonomous underactuated airship. A backstepping controller is designed from the airship nonlinear dynamic model including wind disturbances, and further enhanced to consider actuators saturation. Control implementation issues related to airship underactuation are

Fuzzy path tracking control for automatic steering of vehicles
Robotics and Autonomous Systems, 2003Abstract In this paper, the path tracking (PT) control for automatic steering of vehicles is studied. The Takagi–Sugeno (T–S) fuzzy model of vehicle obtained from a nonlinear model is considered and a fuzzy controller is designed. The stability analysis is discussed using Lyapunov’s approach combined with the linear matrix inequalities (LMI) approach.
