To enhance vehicle maneuverability and stability, a controller with 4-wheel steering (4WS), electronic stability control (ESC) torque vectoring device (TVD) under constraint on the front slip angles is designed in this research. In controller, allocation method adopted to generate yaw moment via 4WS, ESC TVD. If angle added for generating moment, performance of can be further deteriorated. This...

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...

In order to eliminate the interference and coupling among automobile chassis electronic control subsystems, an integrated decoupling control approach based on neural network inverse method was proposed. The integration of active front steering (AFS), direct yaw moment control (DYC) and active suspension (ASS) was studied. According to Inter-actor algorithm, the reversibility of chassis system w...

With the increase of wind turbine dimension and capacity, the wind turbine structures are subjected to prominent loads and fatigue which would reduce the lifetime of wind turbines. Individual pitch control (IPC) is used in this paper to attenuate the blade root bending moment and the tilt and yaw moments and fatigue. The loading transfer from rotational coordinate system to the fixed coordinate...

For a linear model of active car steering a robust decoupling control law by feedback of the yaw rate to front wheel steering was derived earlier. In the present paper this control law is extended by feedback of the yaw rate to rear wheel steering. A controller structure with one free damping parameter k D is derived with the following properties: i) Damping and natural frequency of the yaw mod...

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 ...
