  • Ride Quality Improvement of AGT Vehicle by Active Secondary Suspension : A Study on Relaxed Lateral Irregularity

説明

This paper describes design of active suspension system for Automated Guideway Transit (AGT) vehicles. The modeling of the AGT vehicles with single axle bogies is carried out first. The constructed vehicle model includes lateral transition, roll and yaw motion for vehicle body, front bogie and rear bogie, respectively. The dynamics of two kinds of actuators that produce lateral force is also considered. H-inf control theory is used to design the controller for the active suspension, which has the advantage on designing frequency dependant controller and on the robustness of the controller. The designed controller is evaluated in simulation study with constructed nonlinear AGT vehicle model from the view points of improving the quality. And it is shown that large lateral irregularity can be accepted when the active suspension applied.
