The approach was evaluated in simulation and validated on a demonstrator vehicle. It is a kind of nonlinear feedback control for lateral error, which makes the tractor follow the desired path by inputting the steering command of the front wheel. This requires the implementation of the device on a vehicle that allows higher velocities than the demonstrator vehicle used. For this reason, the Stanley controller is still widely used in practice for vehicles operating at lower velocities (e.g., mobile robots, indoor and outdoor logistics vehicles, and off-road applications). stanleyHighway.slx those of the individual author(s) and contributor(s) and not of MDPI and/or the editor(s).

When using the Stanley approach, a deviation of 1.21 m occurs as a result of the transition to circular motion since steering into the circle is conducted too late. Visualizing vehicle final path in 2D, Bird's-Eye Scope, and a 3D simulation environment. In: Robotics and Automation (ICRA), 2013 IEEE International Conference on, IEEE, pp 28262832, Aparow VR, Hudha K, Ahmad MMHM, Jamaluddin H (2016) Development and verification of 9-DOF armored vehicle model in the lateral and longitudinal directions. (Zhongxiang Zhu) and E.M.; funding acquisition, Z.Z. https://doi.org/10.3390/vehicles5020034, Seiffer, Alexander, Michael Frey, and Frank Gauterin. Model. Available online. In the California PATH project, a linear controller was used, and demonstrated tracking up to 78 mph[3]. A tractor usually runs at low speed in the course of path tracking operation, so it can be simplified as a two-wheel dynamic model in this paper. Improved pure pursuit algorithm for rice transplanter path tracking. Yu, J.; Guo, X.; Pei, X.; Chen, Z.; Zhou, W.; Zhu, M.; Wu, C. Path tracking control based on tube MPC and time delay motion prediction. The three controllers are optimized by MPGA to obtain the best parameters. Editors Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. https://doi.org/10.1080/02533839.2015.1091276, Coulter RC (1990) Implementation of the pure pursuit path tracking algorithm. Path tracking controller of an autonomous armoured vehicle using modified Stanley controller optimized with particle swarm optimization. This is the proposed controller for the tractor. The maneuver presented here includes a step in the curvature and, thus, in the expected yaw rate at the transition to circular motion. articles published under an open access Creative Common CC BY license, any part of the article may be reused without Editors select a small number of articles recently published in the journal that they believe will be particularly The yaw rate of a vehicle, however, cannot change immediately due to rotational inertia and limited tire forces. The method was originally developed by Gabe Hoffman, a fellow lab-mate of mine at Stanford University as his contribution to the winning teams entry, and is named after the vehicle Stanley. Important note: If there is no fluctuation in theta for -180
