The directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. The dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank mode...

The paper presents a fault tolerant control (FTC) strategy for maintaining the lateral stability of a 4WS4WD autonomous vehicle in presence of an unknown component fault. It is designed using the flatness theory and the backstepping technique, and consists in actively controlling the vehicle’s rearwheel steering system. In a normal situation, only the front-wheel steering actuator is used since...

in front wheels driven vehicles, fuel economy can be obtained by summing torques applied to rear wheels. on the other hand, unequal torques applied to rear wheels provides enhanced safety. in this paper, a model with seven degrees of freedom is considered for the vehicle body. thereafter, power-train subsystems are modeled. considering an electrical machine on each rear wheel, a fuzzy controlle...

This paper presents a nonlinear robust control design procedure for a micro air vehicle, which uses the singular value (μ) and μ-synthesis technique. The optimal robust control law that combines parametric and lumped uncertainties of the micro UAV (unmanned aerial vehicle) which are realized by serial connection of the Kestrel autopilot and the Gumstix microprocessor. Thus, the robust control f...

A feedback controller is analyzed for a tailless Micro Aerial Vehicle (MAV) which is to be used for in-situ sensing of toxic plumes. The vehicle will be tube-launched for rapid deployment. The stability derivatives for the lateral dynamics of the aircraft are determined using a combination of Computational Fluid Dynamics and lifting line theory. The state-space model is found to be both complet...

In this paper, two newly developed driver models are presented. They are applied to the evaluation of two driver assistance systems. First, a longitudinal driver model is developed based on measured driving data, which is subsequently used to evaluate the impact of Adaptive Cruise Control (ACC) vehicles on traffic flow. A lateral driver model based on the model predictive control principle is t...

This document deals with the controlled system of lateral vehicle dynamics regulated in terms of a reference model outputs. The reference model means a simplified mathematical vehicle model, which describes the desired lateral movements of a vehicle. The output of the reference model produces the most optimal trajectory in various driving conditions. The target of the control strategy is to hol...

introduction there is very limited literature describing the association of lateral condyle mass (lcm) fracture of the distal humerus associated concurrently with olecranon fracture. herein, a case is reported of a displaced lcm fracture with displaced olecranon fracture, due to complex trauma while getting out of a vehicle, which was managed by open reduction and internal fixation. conclusions...
