Yaw Stability Control Based On Composite Nonlinear Feedback Controller. CNF Controller

      Аннотация: Active Front Steering (AFS) system is installed for yaw stability control to assist the drivers to keep the vehicle on the desired path. However, the car's system performance may be affected if there is existence of disturbance. Thus, it is necessary to implement a control strategy which is able to improve the transient performance of the tracking control and at the same time able to reject the effect of disturbance. This book proposes a control strategy via combination of Composite Nonlinear Feedback (CNF) and Disturbance Observer (DOB) for yaw stability control to improve the transient performance of the tracking control and to eliminate the influence of external disturbance. The proposed control system is designed for Steer-by-Wire (SBW) vehicle and simulated in Matlab/Simulink software.
