Bir aktif süspansiyon için doğrusal olmayan çeyrek araç modeli kullanılarak yapılan optimal kayma modu kontrolcü tasarımı

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