Direct yaw moment control is an effective means to enhance vehicle stability and handling. The majority of the latest direct yaw moment control works employ sliding mode control to generate the target yaw moment. This paper proposes a new sliding mode-based direct yaw moment control method for simultaneous tracking of desired yaw rate and vehicle side-slip for electric and hybrid vehicles equip...

direct yaw moment control systems (dyc) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the control yaw moment (cym). in order to achieve the superior control performance, intelligent usage of lateral forces is also required. the lateral wheel forces have an indirect effect on the cym and based upon their directions,...

Yaw angle control is an essential function in every autonomous vehicle system. In this paper, a novel yaw angle control method for vehicle is proposed. Because the attitude of vehicle obtained from on-board GPS receiver is not only delayed but also at low rate in comparison with the control frequency of EPS servo drives, it is impossible to use GPS directly in yaw angle control loop. By integra...

Abstract: Robust decoupling of the lateral and yaw motions of a car has been achieved by feedback of the integrated yaw rate into front wheel steering. In the present paper the yaw disturbance attenuation is analyzed for a generic single-track vehicle model. The frequency limit, up to which yaw disturbances are attenuated, is calculated. For specific vehicle data, it is shown that this control ...

Individual pitch control (IPC) for reducing blade loads has been investigated and proven successful in recent literature. For IPC, the multi-blade co-ordinate (MBC) transformation is used to process the blade load signals from the rotating to a stationary frame of reference. In the stationary frame of reference, the yaw error of a turbine can be appended to generate IPC actions that are able to...

SUMMARY Details are given of the static calibration of a hemispherrcal-headed drfferentral pressure yawmeter, 0.6 to 1.2; rn the Mach number range from the xnstrument has a central pitot pressure hole and two pairs of holes m perpendroular planes for flow directron measurement. The results show that ths sensitivity to yaw (for angles up to 8') as determined from pressure differences between opp...

In order to achieve the superior control performance, intelligent usage of lateral forces is also required.

BACKGROUND Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult. METHODS We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an in...

An ultrasonic stimulus induced negative phonotactic steering in the yaw axis of tethered, flying Australian field crickets. The forewings, hindwings and twisting of the thorax generated the forces which induced the yaw turn. However, abdominal ruddering did not contribute to yaw turns. Each aspect of the yaw steering response depended upon the stimulus intensity. At higher ultrasonic intensitie...

In this paper, the composite nonlinear feedback (CNF) technique is applied for yaw tracking control of active front steering system with the objectives to improve the transient performance of yaw rate response. For lateral and yaw dynamics analysis, nonlinear and linear vehicle models are utilized as actual vehicle plant and for controller design respectively. The designed controller is evaluat...
