报告摘要:

   The Series Active Variable Geometry Suspension (SAVGS) offers the benefits of a full, active suspension system and the simplicity of a passive system. The SAVGS combines the passive and active suspension technologies in a novel solution to achieve performances similar to ideal active suspensions while preserving many of the benefits offered by passive systems. Moreover, it can co-operate with the other active systems in the vehicle, such as ABS and active seat belt system and can use the same sensors and signals. In this talk, I will present our recent research that the implementation of an overall control approach for the SAVGS, for the improvement of ride comfort and road holding at high-frequency vehicle dynamics and the improvement of chassis attitude motions at low-frequency vehicle dynamics. It proposes a promising technique for the integration of an H-infinity controller and a chassis attitude controller, which aims to achieve multi-objective control through the use of one control scheme. Several events of simulations will be provided to verify that the full-car overall control scheme of the SAVGS tackles the ride comfort, road holding and chassis control objectives simultaneously.
