Automobiles are becoming more and complex as multiple control systems integrated into the vehicle platform. This paper investigates coordination of active rear steering (RWS) torqu...

25 ABSTRACT This paper presents a comparative assessment of modern and intelligent controllers based on time response specification performance for a yaw control of an aircraft system. The dynamic modeling of yaw control system is performed and an autopilot that controls the yaw angle of an aircraft is designed using two controller design methods. The mathematical model of the system is derived...

This paper investigates the coordination of active front steering and rear braking in a driver-assist system for vehicle yaw control. The proposed control system aims at stabilizing the vehicle while achieving a desired yaw rate. During normal driving situations, active steering control is involved for braking collaborate together to ensure vehicle stability. The coordination of these actuators...

In control theory, a controller parameter-tuning method called virtual reference feedback tuning (VRFT) is proposed. VRFT can tune using single experimental data. If be applied to vehicle, the yaw-rate adequately tuned without need for vehicle model. Therefore, this study expands results of realize desired autonomous vehicles. The key point proposed auto-tuning gain-schedule proportional–integr...

Soldier-portable UAVs enhance combat situational awareness by providing an over-thehorizon surveillance platform. This advantage can be multiplied by using multiple microhelicopters (< 20 g, < 20 cm) that operate cooperatively to obtain synoptic vantage points. Cooperative control of multiple helicopters using theoretically justified control laws requires a mathematical model of micro-helicopte...

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...

This paper presents a controller based on fuzzy-logic to ensure simultaneously vehicle handling and stability. The developed controller generates the suitable yaw moment which is obtained from the difference of the brake forces between the front wheels so that the vehicle follows the target values of the yaw rate and the side slip angle. The simulations results show the effectiveness of the pro...

Abstract: A car driver needs at least five hundred milliseconds before he can react to unexpected yaw motions. During this time the uncontrolled car may produce a dangerous yaw rate and sideslip angle. Automatic steering control for disturbance rejection is designed such that it bridges over the driver reaction time, but returns the full steering authority to the driver thereafter. The solution...
