Fuzzy controlled nonlinear Semi-active suspension systems

Ride comfortability of vehicle is a big challenge for the automotive industries and design engineers. The suspension system is the major source of providing comfortability by absorbing vertical vibrations. This paper presents modeling of the non-linear semi-active suspension system equipped with Magneto Rheological damper. Simulation of the designed model is performed in Simulink. A comparative analysis of the Simulink response shows the difference between linear and non-linear model. It has also shown that fuzzy logic controller has improved the performance of the system.
