Magnetic reluctance force actuators offer high force densities and dynamics as well as energy-efficient operations. A relevant automotive target application initiates a systematic magnetic circuit design using equivalent networks and Finite-Element-Method. Dynamic models account for the electro-magneto-mechanic properties of the reluctance force actuators and provide a basis for modern control strategies. State-space, norm-based or flatness-based controller, respectively ensure robust control, while feed-forward action accounts for trajectory quality. Application of the proposed design and control procedures yields reluctance force actuators proving themselves successfully as vibration shaker for automotive squeak and rattle tests.
