Abstract

Giant Magnetostrictive material (GMM), with the properties of fast response, great energy density and high Curie temperature, has potential to be applied to flow control, especially in designing of high speed servo valve working in severe circumstance. The Giant Magnetostrictive Actuator (GMA) is the component to produce tiny displacement precisely. It is the key component of high speed servo valve based on GMM. In order to establish a precise model of GMA, traditional linear time-invariant system model of the GMA can't describe the actuator displacement accurately. To predict the time delay and change law more effectively, the first order inertia and delay links are employed in the system model. The correctness and stability of the model are tested by a series of experiments. The traditional levy method is combined with Genetic Algorithm to identify the proposed model.
