Abstract

Magnetorheological fluids (MR) are capable of changing their rheological properties when a magnetic field is applied. One of the most important applications of the MR fluid is in vibration dampers, mainly used in construction, automobiles and other mechanical systems subjected to excitations that cause unwanted vibrations. This work aims to contribute to the field of vibration control in vehicular suspensions using MR dampers, evaluating the performance of fuzzy and optimal (LQR) controllers.
