Abstract
The efficiency of a given direct-drive electromagnetic active suspension system for automotive applications is investigated. A McPherson suspension system is considered where the strut consists of a direct-drive brushless permanent magnet tubular actuator in parallel with a passive spring and damper. This suspension system has besides delivering active forces the possibility of regenerating power due to imposed movements. An LQR controller is developed for improvement of comfort and handling (dynamic tire load). Finally, the overall efficiency of the system is simulated for various road profiles.
