A fixed-wing aircraft that is capable of low airspeed, high angle of attack flight can serve an expanded range of mission goals. A typical propeller-driven small unmanned aircraft can be equipped with an engine that provides greater thrust than airplane weight; in post-stall states, the aircraft then depends on propeller backwash over the tail for control moment generation. Due to this dependen...

Abstract: In this paper a three dimensional non-linear model has been derived to describe the dynamics of an unstable moment exchange unicycle robot. The robot uses a driving wheel to provide stabilization in longitudinal direction, while a second moment exchange wheel with a large inertia is used for stabilization in lateral direction. For validation purposes, the resulting equations of motion...

The purpose of this study was to determine the source of postural instability in labyrinthectomized cats during lateral head turns. Cats were trained to maintain the head in a forward orientation and then perform a rapid, large-amplitude head turn to left or right in yaw, while standing freely on a force platform. Head turns were biomechanically complex with the primary movement in the yaw plan...

An adaptive cruise control (ACC) system can reduce driver workload and improve safety by taking over the longitudinal of vehicles. Nowadays, with development range sensors V2X technology, ACC has been applied to curved conditions. Therefore, in curving car-following process, it is necessary simultaneously consider performance, ride comfort, fuel economy lateral stability vehicle. The direct yaw...

Considering driving safety and comfort, this paper proposed a roll and yaw integrated control method utilizing four wheel steering based on disturbance observer (hereinafter DOB) and 2-degree-of-freedom (hereinafter 2DOF) control approach. Firstly, vehicle model for controller design as well as the desired roll and yaw motion were explained; then the controller design was carried out based on t...
