Coordinated Compensation Between Active and Semi-Active Actuators for Suspension Control System

This paper presents coordinated compensation schemes between active and semi-active actuators in suspension control system. Generally systems, have been adopted to generate a force calculated by controller. However, actual vehicles physical constraints such as maximum force, bandwidth force-velocity limitation. On the other hand, actuator can be good alternative one view of despite it cannot an force. performance is limited half ones. Hence, necessary compensate In this paper, assumed that vehicle has both actuators. A needed enhance ride comfort generated linear quadratic regulator (LQR). The controller designed with 2-DOF quarter-car model applied into 7-DOF full-car one. To actuators, several are proposed. simulation on package show proposed effective reducing over wider range frequencies.
