According to the design demands of the steer-by-wire system, a PIlDm controller based on fractional calculus was proposed. Aligning controller and steering controller were respectively designed to achieve the aligning and steering function of the front wheel steering module, which can ensure the robust of the steer-by-wire system during the special ranges of frequency. The five design parameters of fractional PIlDm controller were achieved by optimization method. Oustaloup method was used to approximate the fractional PIlDm controller and simulation model was achieved, which can be used in Matlab/Simulink. Computational simulations of the control system were carried out and simulation results showed the effectiveness of the control method to improve the robust of the steering-by-wire system.

In this paper, a stability control method based on active front steering control is proposed to steer by wire system (SBW). The proposed control system consists of an inner-loop angle tracking controller and an outer-loop controller. The inner-loop controller contributes to front steering angle tracking, and it is designed by PID control. The outer-loop controller restrains the effect of disturbance by feeding a compensation steering angle, and it is designed by using Improved Active Disturbances Rejection Control (IADRC) with less adjusted parameters than Active Disturbances Rejection Control (ADRC). Finally, the effectiveness of the proposed method is evaluated via numerical simulation and vehicle test. The obtained results show that the proposed controller can improve the handling stability of the SBW system. To a certain extent, the study results promote the research and application of SBW system.

In this paper, active disturbance rejection control method is used to implement the steering angle following control of steer-by-wire system for the simplification of controller designing. The dynamic model of steering performing system is established, and then a second order active disturbance rejection controller is designed to control the steering angle. On the electric vehicle with steer-by-wire system, the angle following test of steering performing system is carried out under the control of the second order active disturbance rejection controller. The results show that the designed active disturbance rejection controller can restrain the effect of system resistant force on the accuracy of angle following and meet the requirement of steer-by-wire system to the steering angle following function. At the same time, there isn’t necessary to get the accurate data of steering system and the design process of controller becomes simple with adopting active disturbance rejection control method.

To improve the maneuverability, stability, and reliability of the steer-by-wire system, a two-way H∞ control method with a fault-tolerant module is proposed in this paper. First, a two-way H∞ control scheme is proposed. Two controllers are designed in this scheme: one is used as a feedback controller as a general practice to stabilize the system and detect the tracking error; the other is used as a feed forward controller to make the output of the system follow the driver’s steering intention rapidly and precisely. Second, a fault-tolerant module aiming at front wheel angle sensor which is an important feedback signal to the system is added to improve the reliability of the system. A revised Kalman filter is applied in the fault-tolerant module to reconfigure the front wheel angle as a reference value and a substitute when the sensor fails, thus replacing hardware redundancy by software redundancy in a cost-effective way. Lastly, simulations by Matlab/Simulink and CarSim software and hardware-in-the-loop experiments are conducted and effectiveness of the proposed control method is demonstrated by simulation and experimental results and numerical analyses.
