Predictive Control Algorithm Based on Dynamic Stability Matrix Method for DSC

Based on the study of the dynamic characteristics, the observers for tire force, lateral and longitudinal velocity, and vehicle stability matrix are proposed. The stability matrix is used to predict the stability of the vehicle involving the vehicle dynamic constraints and the active brake pressure modulator. Integrating the proposed method into the state feedback control logic, the predictive control algorithm is brought forward. The simulation results show that the over shoot is restrained and the oscillatory of the steering handling character is overcome.
