Abstract:

This paper addresses aspects of model development and control design for smart structure which utilize piezoelectric, electrostrictive, magnetostrictive or shape memory alloys. The advent of these materials as sensors and actuators provides the opportunity for designing systems with improved performance while reducing weight, hardware and power requirements. At high drive levels, however, all of these materials exhibit nonlinear constitutive relations and varying degrees of hysteresis which must be accommodated to realize their full potential in smart structures. We outline a variety of modeling techniques and illustrate their use in feedback, feedforward and adaptive control designs.
