It is a difficult and important project to coordinate active front steering (AFS) and direct yaw moment control (DYC), which has great potential to improve vehicle dynamic stability. Moreover, the balance between driver’s operation and advanced technologies’ intervention is a critical problem. This paper proposes a human-machine-cooperative-driving controller (HMCDC) with a hierarchical structu...

Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far.&#10In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. &#10This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be ...

This paper proposes the development of an advanced fuzzy logic controller which aims to perform intelligent automatic control of the yaw movement of wind turbines. The specific fuzzy controller takes into account both the wind velocity and the acceptable yaw error correlation in order to achieve maximum performance efficacy. In this way, the proposed yaw control system is remarkably adaptive to...

In order to solve the problem of vehicle stability control after a single-wheel brake failure in brake-by-wire system, strategy braking force redistribution with yaw moment is proposed ensure efficiency and vehicles. this strategy, two-layer architecture adopted. upper layer control, fault factor introduced represent real-time degree wheel, driver’s intention perceived through pedal travel spee...

This paper presents an active steering system designed to ensure both the curving performance and running stability of a vehicle. Electro-hydraulic actuators installed in place anti-yaw dampers generate yaw moment between carbody bogie. The detects curves with gyroscopes mounted on configuration enables reduction wheel/rail lateral force without requiring complicated mechanical links bogies. al...

Natural wind is stochastic, being characterized by its speed and direction which change randomly and frequently. Because of the certain lag in control systems and the yaw body itself, wind turbines cannot be accurately aligned toward the wind direction when the wind speed and wind direction change frequently. Thus, wind turbines often suffer from a series of engineering issues during operation,...

The application of conventional wind turbines on board a vessel creates a number of new challenges for turbine control systems. Thrust force is used in marine applications as an additional control variable for propulsion of the vessel. Variability of the wind speed and wind direction, together with the yaw rate and range constraints, impose strong requirements on the turbine control system. A n...
