Robust controller design techniques have been applied to the field of vehicle control to achieve many different performance measures: robust yaw rate control [1], robust lateral positioning using one [2, 3] or more [4-6] driver inputs, robust observer design, and so on. A difficulty with many published approaches is to obtain an adequate description of the model uncertainty. Most bounds on plan...

The liquid cargo contained in a partly-filled road tank vehicle is prone to dynamic slosh movement when subjected to external disturbances. The slosh behavior has been identified as a significant factor impairing the safety of liquid cargo transportation. The laboratory experiments have been conducted for analyzing fluid slosh in partly filled tanks. The experiment results measured under forced...

This paper presents a concept of platoon movement of autonomous vehicles (smart cars). To be able to do research to the stability of an AGV string, a car-following model is being determined. To do this, first a single vehicle is modeled and since all cars in the platoon have the same dynamics, the single vehicle model is copied ten times. To control this string, equal P(I)D controllers are appl...

As vehicle testing on existing vehicles is both time and resource consuming, the work of testing safety algorithms on vehicle is desired to be made more efficient. Therefore the goal of this thesis is to study and develop a vehicle simulation model that can simulate desired dynamics of existing and non-existing vehicles. The developed model consist of two areas of application: slow dynamics and...

The tire-road friction coefficient is critical information for conventional vehicle safety control systems. Most previous studies in tire-road friction estimation have only considered either longitudinal or lateral vehicle dynamics which tends to cause significant underestimation of the actual tire-road friction coefficient. In this paper, the parameters, including the tireroad friction coeffic...

This paper presents a detailed account of computational fluid dynamics (CFD) simulations undertaken to investigate the influence of intake (ventilation) air velocities on the flow patterns of diesel particulate matter (DPM) generated by a man-riding vehicle operating in a straight rectangular cross section tunnel in an underground coal mine. The simulation results are validated against an earli...

Formation control for multiple vehicles has become an active research area in recent years. Generally there are three approaches to this problem, namely leaderfollowing, behavioral, and virtual structure approaches. In this paper, formation control ideas for multiple spacecraft using virtual structure approach are presented. If there is no formation feedback from spacecraft to the virtual struc...

This article describes the design, modeling and identification of the main hydrodynamic parameters of an underwater glider vehicle is presented. The equations describing the dynamics of the vehicle is obtained from the Euler-Lagrange method. The main hydrodynamic parameters were obtained considering the geometry of the vehicle and its operating characteristics. Finally, simulation open loop sys...

Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances in proper running of wheelset on track. To analyze the noise, Kalman filter is used based ...
