Abstract :
The bridge circuit method and observer method for giant magnetostrictive self-sensing actuator are introduced. The models of the two methods are established. The non-linear model is built up in the bridge circuit, while the amplifier and filter circuit are designed in the simulation which provides the theory for the experiment. The validity of the observer is proved by the comparison of calculative result with experimental result.
