|Title:||Modeling and control of piezoelectric actuator systems||Authors:||Huang, S.N.
|Issue Date:||2011||Citation:||Huang, S.N.,Tan, K.K. (2011). Modeling and control of piezoelectric actuator systems. Piezoelectric Actuators : 117-138. ScholarBank@NUS Repository.||Abstract:||In this chapter, common configuration of the piezoelectric actuator (PA) systems, their mathematical models as well as control schemes will be discussed. One major source of uncertainties in PA design and application is the hysteresis behavior which yields a rate-independent lag and residual displacement near zero input, reducing the precision of the actuators. For eliminating the effects of the hysteresis phenomenon, we have to build the model of a PA system. Several representative models will be discussed in the chapter: the Maxwell model, the time delay hysteresis model, the Jiles-Atherton model, the Preisach model and the dynamical LuGre Model. The controller design is based on the model obtained. The simulation study is given to show the effectiveness of the proposed control scheme. © 2011 by Nova Science Publishers, Inc.
