Abstract
Vibration by road surface gives the damage or deterioration of luggage. In terms of protecting the quality of the luggage, the development of technology of vibration suppression is demanded. Therefore, studies on the active suspension have been carried out actively. However, the parameter changes of the weight of the luggage is larger, suspension performance varies by the weight of the luggage. Therefore, it is effective to develop robust controller for the active suspension based on the weight of the luggage. As robust control design to parameter variation for such a control object, Simple Adaptive Control is proposed. Simple adaptive control is a system design method based on a control theory by tuning the adaptive gains in the controller. Control gains of the controller are adjusted automatically to adapt to changes to the weight of the luggage, it is possible to maintain good performance to prevent vehicle vibrations. This study confirmed that the active suspension using a simple adaptive control have better performance than passive suspension.
