STABILIZATION OF AN UNDERWATER VEHICLE
IFAC Proceedings Volumes, 2005 Abstract We present a sliding mode based control law for stabilizing an underactuated underwater vehicle (UUV) moving in a horizontal plane. The novelty of the proposed control law is that we exploit the dynamics of the vehicle to define three sliding surfaces, at whose intersection the system is asymptotically stable.

The Impact of Hollow Wear on the Stability of High-Speed Railway Vehicles
Applied SciencesHollow wear on wheels is a common form of surface damage often observed in high-velocity vehicles. It is widely recognized that hollow wear of the wheel tread degrades the dynamic performance of rail vehicles, especially in the issue commonly referred to

The development of a pseudo-nyquist analysis technique for hybrid sampled-data control systems [PDF]
The stability characteristics of a launch vehicle, as a function of gain and phase variations at the thrust vector controller, cannot be obtained using classical sampled-data control theory if the launch vehicle attitude control system contains both ...

Rationing Rules and Outcomes: The Experience of Singapore's Vehicle Quota System [PDF]
Since 1990, Singapore has sought to control motor vehicle ownership by means of an auction quota system, whereby prospective vehicle buyers need to obtain a quota license before they can make their purchase. This paper assesses the success of the vehicle
