Abstract It is a striking fact that the path tracking accuracy of autonomous vehicles based on active front wheel steering poor under high-speed and large-curvature conditions. In this study, an adaptive control strategy coordinates direct yaw moment proposed model predictive algorithm. The recursive least square method with forgetting factor used to identify rear tire cornering stiffness updat...

Accurate measurements from sensors measuring the vehicle’s lateral behavior are vital in todays vehicle dynamic control systems such as the Electronic Stability Program (ESP). This thesis concerns accurate plausibilisation of two of these sensors, namely the yaw rate sensor and the lateral acceleration sensor. The estimation is based on Kalman filtering and culminates in the use of a 2 degree-o...

In this paper, dynamics and stability of an articulated vehicle in the yaw plane are examined through analysis, simulations, and vehicle testing. Control of a vehicletrailer combination using active braking of the towing vehicle is discussed. A linear analytical model describing lateral and yaw motions of a vehicle-trailer combination is used to study the effects of parameter variations of the ...

Flow behavior and aerodynamic performance of a small-scale joined-wing unmanned aerial vehicle (UAV) was studied experimentally numerically under various pitch yaw angle combinations in subsonic flow conditions. Selected numerical results are compared against experimental obtained using surface oil visualizations force measurements, with additional simulations expanding the range combined confi...

The precise control of body posture by turning moments is key to elevated locomotor performance in flying animals. Although elevated moments for body stabilization are typically produced by wing aerodynamics, animals also steer using drag on body appendages, shifting their centre of body mass, and changing moments of inertia caused by active alterations in body shape. To estimate the instantane...
