AB  - The Series Active  Variable Geometry Suspension (SAVGS)  which  has  been  recently  proposed  shows  promising potential  in  terms  of  suspension  performance  enhancement, limited power consumption and so on. In this paper, the control aspects of a full-car prototype with the front axle retrofitted by the   SAVGS,   which is   developed   to   validate   the   practical feasibility  of  the  novel  mechatronic  suspension,  are  addressed. Two  12  Vdc  batteries  and  one  DC/AC  inverter  constitute  an independent  power  source  that  supplies  the  overall  embedded mechatronic  system,  with  two  AC  rotary  servo  motors  driving the   single   links   (in   the   SAVGS)   at   two   front   corners, respectively.A   robust   control   scheme,   with   an   outer-loop H-infinity  control  and  an  inner-loop  actuator  velocity  tracking control,  is  synthesized  to  enhance  the  vehicle  ride  comfort  and road holding performance. Numerical simulations of the full-car prototype, withthetypical road events of a 2 Hz harmonic road, and a speed humptested, are performed. Nonlinear simulation results     provide     the     potential     suspension     performance improvement contributed by the SAVGS and the power usage in the  batteries,  which  will  be  compared  in  the  future  with  the upcoming experimental testing results of the prototype on-road driving.
