MATLAB simulation of semi-active skyhook control of a quarter car incorporating an MR damper and a fuzzy logic controller
This paper investigates the performance of skyhook control designed for use with a magnetorheological damper through MATLAB simulation. The fuzzy logic simulation was observed for increased performance over conventional passive damper systems, and for behaviour in keeping with the skyhook control theory. Once it was established that the controller was accurately simulating skyhook control, the overall performance and system response was analysed. It was found that the semi-active system improved the response of the vehicle sprung mass at the expense of unsprung mass control, proving that greater occupant comfort can be achieved via semi-active suspension control.
