A non-linear quarter car model is used in this study for developing a control algorithmfor an active suspension system. The control method used, is optimal sliding modecontrol, along with feedback linearization technique for compensating the non-linearaspects of the plant. In addition to the work in recent literature that applies thesecontrol methods, estimation of the static suspension deflection, i.e., vehicle sprungmass is performed. Through simulation results, it is shown that correct information ofvehicle sprung mass, compared to taking it as a constant parameter in control design,improves the performance of the controller. This information, in turn, reduces thesprung mass acceleration level and enhances ride comfort.
