Abstract

Magnetostrictive devices have some potential as smart actuators, where fast responses of the actuators and low supply voltages are required. For many applications it is desirable that the actuators show a linear behavior. Although the magnetostrictive e ect is a nolinear one, one can obtain linearity approximately by applying a magnetic bias and mechanica prestress in the material. An additional improvement is achievable by active control of the device. This contribution deals with the mathematical modeling of a magnetostrictive actuator, which can be modeled as a rod. A control scheme for the actuator is presented, which not only stabilizes the mathematical model of the magnetrostricive rod, but leads to an excellent tracking behavior, also.
