One of the main systems for ground vehicles is Electric Power Assisted Steering (EPAS). Due to its importance, a redundant system usually implemented. This solution remain however expensive, especially small urban cars. paper proposes an alternative fail-safe control algorithm using this time differential braking. Controlling each brake apart generates yaw moment enabling turning vehicle. Optim...

Attitude control systems for autonomous underwater vehicles are often implemented with separate controllers for pitch motion in the vertical plane and yaw motion in the horizontal plane. We propose a novel time-varying model for a streamlined autonomous underwater vehicle that explicitly displays the coupling between yaw and pitch motion due to nonzero roll angle and/or roll rate. The model fac...

This paper introduces the basic control methods of a Biomimetic Underwater Vehicle, and a neural network model is designed for the vehicle. The concerned vehicle is propelled by two undulating long-fins installed on both sides. Ten motors are employed to drive the long-fin and sine wave function is employed for motor control. The real-time control system is designed for controlling the long-fin...

A robust yaw stability control system is designed to stabilize the vehicle yaw motion. Since the vehicles undergo changes in parameters and disturbances with respect to the wide range of driving condition, e.g., tire-road conditions, a robust control design technique is required to guarantee system stability. In this paper, a sliding mode control methodology is applied to make vehicle yaw rate ...

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...

This paper presents a method to design path tracking controller with four-wheel independent braking (4WIB), drive (4WID) and steering (4WIS) systems equipped in in-wheel motor-driven electric vehicles (IWM-EVs). Generally, it is difficult calculate the angles of 4WIS braking/traction torques 4WIB/4WID for control. Moreover, there have been limitations an error dynamics-based controller, which r...

As wind turbine diameters continue to increase, the cyclic loading experienced by blade due shear and yaw misalignment increases dramatically hindering development of larger more efficient turbines. Based on current literature, controlling a section trailing edge was found reduce loading. To quantify load control capability flap (TEF), an experimental rig designed evaluate TEF 3.5-m-diam operat...

Vehicle which are turning or maneuvering at high speeds are susceptible to sliding and subsequently deviate from desired path. In this paper the dynamics governing the Yaw/Roll behavior of a vehicle has been simulated. Two different simulations have been used one for the real vehicle, for which a fuzzy controller is designed to increase its directional stability property. The other simulation i...

A normalization method of road adhesion coefficient and tire cornering stiffness is proposed to provide the significant information for vehicle direct yaw-moment control (DYC) system design. This carried out based on a fractional-order multi-variable gray model (FOMVGM) long short-term memory (LSTM) network. FOMVGM used generate training data testing LSTM network, network employed predict with ...
