Our ability to keep track of objects in the environment, even as we move, has been attributed to various cues including efference copies, vestibular signals, proprioception, and gravitational cues. However, the presence of some cues, such as gravity, may not be used to the same extent by different axes of motion (e.g., yaw vs. roll). We tested whether changes in gravitational cues can be used t...

This paper presents a novel lateral stability control system for electric vehicle based on sideslip angle estimation through Kalman filter using the integration of a single antenna GPS receiver and yaw rate sensor. Using multi-rate measurements including yaw rate and course angle, time-varying parameters disappear from the measurement equation of the proposed Kalman filter. Accurate sideslip an...

Abstract—In this paper we extend the Park and Jensen wake model to include the effects of yaw misalignment and wake deflection of wind turbines. We perform a numerical study to find the optimal values of induction factor and yaw misalignment angle of wind turbines in a single row of a windfarm for achieving the maximum total power with wake effects. Our study shows that the maximum power is ach...

In avian bipeds performing steady locomotion, right and left limbs are typically assumed to act out of phase, but with little kinematic disparity. However, outwardly appearing steadiness may harbor previously unrecognized asymmetries. Here, we present marker-based XROMM data showing that guineafowl on a treadmill routinely yaw away from their direction of travel using asymmetrical limb kinemati...

In this paper, a novel yaw moment control system is proposed to improve vehicle’s handling and stability. The control system includes reference model, DYC controller, Distributer, and Smith predictor. The reference model is used to obtain the desired yaw rate. The DYC controller determines the desired yaw moment by means of sliding-mode technique. The Distributer, based on maneuverability and c...

More and more popular electric vehicles are excellent application platforms for steerby-wire (SBW) system. Handling stabilities and active safety are greatly improved when SBW is adopted in electric vehicle. The proposed new architecture of SBW electric vehicle is introduced, its dynamics model is built after the principle and structure. The algorithm achieves the yaw motion of electric vehicle...

An enhanced data driven model-free adaptive yaw control tracking control scheme is proposed for the yaw channel of an unmanned-aerial-vehicle (UAV) helicopter which is non-affine in the control input in this paper. Through dynamic linearization and observer techniques, the proposed control algorithm is only based on the pseudo-partial derivative (PPD) parameter estimation derived online from th...

An exploratory computational investigation using RANS & URANS was carried out to understand the aerodynamics around an isolated single rotating wheel with decreasing ground proximity. The wheel was initially modelled in free air conditions, then with decreasing ground proximity and increased yaw angle with rotational speeds. Three speeds of rotation were applied to the wheel so that the effect ...
