| Summary: | In this paper, the development of a novel semiactive
suspension control of quarter car model using fuzzy logic
based controller has been done. The proposed quarter car model
can be described as a nonlinear two degrees of freedom system,
which is subject to system disturbances from different road
profiles. In order to implement the suspension system
experimentally, the magneto rheological (MR) fluid has been used
as adjustable damper. The MR damper is a control device that
consists of a hydraulic cylinder filled with magnetically
polarizable particles suspended in a liquid. The MR dampers
rapidly dissipate vibration by absorbing energy. In this work, a
proportional integral derivative, a fuzzy logic and hybrid
controllers are used to control the semi-active car suspension
system. Results show that both fuzzy logic and hybrid controllers
are quite suitable to eliminate road disturbances to the suspension
system considerably as compared to the conventional PID
controller. |
