Multi-objective control of dynamic chassis considering road roughness class recognition
For the control of the semi-active suspension with continuously adjustable damping, in addition to the ride comfort, the handling and stability requirements also need to be considered，but these needs are often not met at the same time. This contradiction put forward a big challenge for the design of the controller, especially in the face of complex working conditions. Traditional controllers are mainly aimed at restraining vehicles’ attitude caused by the changes in the environment or vehicle motion state, they lack adaptive adjustment to disturbances with certain statistical characteristics, so the control has a certain lag. In order to solve this problem, Adaptive Road Disturbance Fuzzy Control (ARDFC) of the semi-active suspension with continuously adjustable damping considering road roughness class identification is proposed in this paper.
