Bicycle Rider Control Modelling for Path Tracking

IFAC-PapersOnLine, 2015
Abstract Rider models are employed to gain insight into bicycle rider steering behaviour and to improve characteristic properties of bicycles. In this paper, stability properties as well as basic dynamic characteristics of the passive (uncontrolled) bicycle-rider system and consequences on the rider control modelling are addressed. In particular, the

Multi-under-Actuated Unmanned Surface Vessel Coordinated Path Tracking

Sensors, 2020
Multi-under-actuated unmanned surface vehicles (USV) path tracking control is studied and decoupled by virtue of decentralized control. First, an improved integral line-of-sight guidance strategy is put forward and combined with feedback control to ...

A Model Predictive Controller with Longitudinal Speed Compensation for Autonomous Vehicle Path Tracking

Applied Sciences, 2019
Autonomous vehicle path tracking accuracy faces challenges in being accomplished due to the assumption that the longitudinal speed is constant in the prediction horizon in a model predictive control (MPC) control frame.

On Model Predictive Path Following and Trajectory Tracking for Industrial Robots [PDF]

, 2017
In this article we show how the model predictive path following controller allows robotic manipulators to stop at obstructions in a way that model predictive trajectory tracking controllers cannot.
