Robust Control System Design for Vehicle Stability Considering the Roll Dynamics

摘要：

A three Degree of Freedom (3-DOF) vehicle model is established and linearized. The influence of roll morion on the yaw and lateral dynamics is also analyzed. Choosing the slip-angle, yaw rate, roll angle and roll rate as the feedback variables to be traced, a robust multi-objective tracing controller is designed based on the linearized 3-DOF vehicle model with the H∞ control theory. So the four objectives are optimized simultaneously by coordinating the actions of active steering and yaw moment. Numerical simulations demonstrate that the 3-DOF vehicle model based integrated control scheme can well constrain the roll oscillation compared with the one designed based on a 2-DOF vehicle model. The effect of roll oscillation on the other performances is also minimized and the vehicle handling and stability are improved then.
