| Abstract: | Present work aims at developing an active suspension for a passenger car by designing a controller using linear quadratic optimal control theory, based on two different control approaches [conventional method (CM), acceleration dependent method (ADM)]. Performance of the active suspension system of a quarter car model with 3 degrees-of-freedom with two control approaches has been compared with that of passive one. Active suspension system had a better potential to improve both the ride comfort and road holding, since the passenger acceleration has been reduced for active CM system (19.58%) and for active ADM system (34.08%) compared to passive one. Also suspension travel has reduced (37.5%). |
