Abstract

All electric-damper is now a fashionable method for vehicle balance as the development of the high power linear and motor drive system allow the fast and efficient solution to dampers. The conventional damper is then replaced by active motor drive that provides faster response than the conventional system. In this paper, an LMFC method is proposed to provide a better control method for the four dampers that is located in the vehicle. The 4-coordinate control is difficult as they are closely related to each other. The heave position, pitch and roll angle are the main concerns to keep consistent for the passenger's comfort and ride performance. To achieve this goal, an effective LMCF is investigated and applied to the active damper system, with its simplicity and reliable for implementation. For the active damper system, the inner loop is with PD control to eliminate the disturbances and nonlinearities, while the outer loop is with linear model following control to track the required dynamic performance. The computed results verify the proposed control methods, and the dynamic response of the active damper systems is studied by optimization.
