A convergence-based anti-windup control strategy is presented and demonstrated by the example of aircraft yaw control problem.

When the driving road surface condition suddenly changes from dry to wet, the driving wheels will slip due to much lower coefficient of friction, and thus cause the vehicle to skid. Unlike the popular anti-brake system which applies differential braking to wheels, the presented ant-skid Control properly distributes torques to wheels without braking. In comparison with many recently developed an...

This paper describes a unique capacitively-sensed MEMS-based gyroscope, which utilizes rotating carrier rotate as driven force and responds to an external angular rate of yaw due to the Coriolis Effect. The basic construction and operating principles of the gyroscope are described and illustrated. MEMS-based gyroscope output is presented at different yaw angular acceleration. The raw results ob...

A curve negotiation task at a prescribed and constant velocity was performed in the presence of external disturbances. The driver’s goal was to simultaneously minimize the heading error and lateral position error. The present paper investigates the separate contributions of the road tracking and the disturbance to the heading and position errors, and more important, the effect of motion on thes...

Robust adaptive control of underwater vehicles in 6 DOF is analyzed in the context of measurement noise. The performance of the adaptive control laws of Sadegh and Horowitz (1990) and Slotine and Benedetto (1990) are compared. Both these schemes require that all states are measured, that is the velocities and positions in surge, sway, heave, roll, pitch and yaw. However, for underwater vehicles...

Non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. In this paper, an optimal linear quadratic regulator (LQR) controller for roll-yaw dynamics to articulated heavy vehicles is developed. For this purpose, the equations of motion obtained by the MATLAB sof...

Aiming at a class of multiple-input multiple-output (MIMO) system with uncertainty, a sliding mode control algorithm based on neural network disturbance observer is designed and applied to ship yaw and roll joint stabilization. The nonlinear disturbance observer is finished by radial basis function neural network and with that a terminal sliding mode control algorithm is proposed. The asymptoti...

Trajectory tracking is an important aspect of autonomous vehicles. The idea behind trajectory tracking is the ability of the vehicle to follow a predefined path with zero steady state error. The difficulty arises due to the nonlinearity of vehicle dynamics. Therefore, this paper proposes a stable tracking control for an autonomous vehicle. An approach that consists of steering wheel control and...

Direct Yaw Moment Control (DYC) is an effective way to alter the behaviour of electric cars with independent drives. Controlling torque applied each wheel can improve handling performance a vehicle making it safer and faster on race track. The state-of-the-art literature covers comparison various controllers (PID, LPV, LQR, SMC, etc.) using ISO manoeuvres. However, more advanced important chara...
