An MPC-based manoeuvre stability controller for full drive-by-wire vehicles
- 11 Downloads
Aiming at the actuator time delay caused by the drive-by-wire technology, a novel manoeuvre stability controller based on model predictive control is proposed for full drive-by-wire vehicles. Firstly, the future vehicle dynamics are predicted by a twodegree-of-freedom vehicle model with input delay. Secondly, in order to prevent the vehicle from destabilizing due to excessive side slip angles, the determined ideal yaw rate and side slip angle are tracked simultaneously by optimizing the front wheel angle and additional yaw moment. Moreover, in order to improve the trajectory tracking ability, a side slip angle constraint determined by phase plane stability boundaries is added to the cost function. The results of Matlab and veDYNA co-simulation show that the regulated yaw rate can track the reference value well and the side slip angle decreases. Meanwhile, the trajectory tracking ability is improved obviously by compensating the time delay.
