This paper shows roll and pitch feedback control on a coaxial mini helicopter equipped with a center of gravity steering mechanism. The helicopter carries a minimal set of sensors to measure yaw rate, distance to ground and roll and pitch angle. While yaw rate and distance to ground control are already realized on the helicopter, roll and pitch control including the necessary signal filtering a...

Planing hulls, commonly used in many areas, have different hydrodynamic behavior than the displacement even calm water. Therefore, this makes calculation of maneuvering parameters these hulls appealing. In present study, a planing hull's numerical static drift analyses are performed using unsteady RANS approach to evaluate sway force and yaw moment at angles attack advance velocities. The resul...

Tire longitudinal forces of electrics vehicle with four in-wheel-motors can be adjusted independently. This provides advantages for its stability control. In this paper, an electric is taken as the research object. Considering key factors such velocity and road adhesion coefficient, criterion studied, based on phase plane sideslip angle sideslip-angle rate. To solve problem that vehicles diffic...

This paper describes an integrated autonomous driving (AD) control system for vehicle with four independent in-wheel motors (IWMs). The consists of two parts: the AD controller and chassis controller. These elements are functionally to improve stability path tracking performance. is assumed employ IWM independently at each wheel. implements longitudinal/lateral using proportional-integral(PI) a...
