| Control Of Vehıcle Suspensıon Systems Usıng Mr Dampers
Since power consumption of the semi-active suspensions are less than the active suspensions, they are preferred in many applications. Especially, the semi-active suspension designs equipped with MR dampers give the ability to change the damping coefficient which results in better vibration control. In this thesis, first, the quarter car model is obtained. Then, in order to determine the vibration suspension limits of the ideal semi-active system without MR damper, different control methods such as PID control, fuzzy logic control and sliding mode control were used. Additionally, certain semi-active control methods such as sky-hook were used. Also, certain active control methods were resembled by using semi-active control methods. Then, the mathematical model of the MR damper was obtained and added to system. The effects of the MR damper on the control methods were determined. By using propped models, it was aimed to reach to the real cases.
Finally, the control methods, which best fit the MR damper, where investigated and they were compared by extensive simulations.
