ABSTRACT |
This paper presents a robust controller for four wheel independently-actuated (FWIA) electric ground vehicles to preserve vehicle stability and improve vehicle handling performance. Thanks to the actuation flexibility of FWIA electric ground vehicles, an external yaw moment, which is usually employed to regulate the vehicle yaw and lateral motions, can be easily generated with the torque differences between the left and right side motors.
