Abstract
This paper focuses on the development of partial inverse compensation techniques for linear control design in systems employing magnetostrictive transducers operating in nonlinear and hysteretic regimes. At low drive levels, linear models can be used to characterize strains and forces generated by magnetostrictive transducers with reasonable accuracy. However, at the moderate to high drive levels where transducer performance is optimal, inherent constitutive nonlinearities and hysteresis must be accommodated to achieve the accuracy and speed requirements for high performance applications. Appropriate nonlinear and hysteretic modeling techniques are reviewed and an inverse compensator based on the nonlinear kernel of the model is developed. The performance of the technique is illustrated through numerical examples.
