In this thesis a suspension control study was conducted which has a mechanism capable of applying control force to the spring via a piezoelectric actuator. The spring used in this study will be considered to have a linear and a non-linear region. The control system is implemented using fuzzy logic techniques. The controller will receive sensor data of vertical displacement and vehicle speed and produce the appropriate control force based on some verbal rules. The aim is to construct a device that will give the appropriate values for the best possible depreciation of the disturbances.
