“…The scheme consists of two variable parameter controllers, which are designed for longitudinal and transverse systems with coupling performance. Wang et al [10], based on the optimization technology, designed the fractional order controller by reasonably selecting the constraint conditions, and decoupled the vehicle model with good robustness. Other researchers also apply fractional order control theory to rear steering systems to achieve the desired results [11][12][13].…”

To improve the overall performance of four-wheel steering vehicles under different working conditions and solve the problem of the unbalanced comprehensive control effect of a single controller, a multi-mode optimal decision control system is proposed based on the linear 2-DOF dynamic model of the vehicle, which can make the vehicle have better performance under different working conditions. The system is composed of multiple controllers, in which the self-tuning dual yaw rate feedback controller can create timely feedback and make adjustments according to the driving state of the vehicle, which is optimal under the condition of a small rotation angle at medium and high speeds. The system can match the corresponding controller according to the optimal performance of different control strategies at different speeds and angles. The simulation results show that the multi-mode optimal selection system can make the vehicle perform optimally under different working conditions, and that comprehensive performance is more prominent than that of a single controller.
