THE ATTAINMENT OF RIDING COMFORT FOR A TRACKED AIR CUSHION VEHICLE THROUGH THE USE OF AN ACTIVE AERODYNAMIC SUSPENSION

The feasibility of controlling high speed ground transportation systems through the use of active lifting surfaces was studied. Aerodynamically three dimensional canards are employed to control the pitch and plunge steady-state response of the vehicle and passenger to harmonic guideway excitations. Various control laws are assumed and vehicle and passenger response studied. An optimal solution to the classic regulator problem is found, providing optimal acceleration suppression for two aerodynamic cases. Comparison of vehicle response at 300 miles per hour to the ISO riding comfort standards is made. Except for the optimal cases, all results indicate an uncomfortable and harmful ride would result from the vehicle's response. The optimal control provides a comfortable and safe passenger environment.
