Abstract

Active Yaw Control (AYC) is one of that prominent approaches for lateral dynamic control which ensure the stability for high speed highway cruising. Thus, robustness of the control strategies of an AYC control system is essential. In this project, a new control strategies which integration of feedforward control and composite nonlinear control for AYC control system is proposed for vehicle sideslip and yaw rate tracking control based on active steering. This integrated controller is able to track the desired sideslip and yaw rate for the improvement of vehicle handling and stability performances. Evaluation on the integrated controller is carried out by using MATLAB Simulink where constant cornering and s-shape cornering are tested. The simulation results show the application of this integrated controller for sideslip and yaw rate tracking control. From the results, Feed_CNF PID controller has better performance as compared to Feed_PID with a lower overshoot of 1.531% and settling time of 2.170%.
