Design of a Piezoelectric Actuator Using Topology Optimization

This study investigates the optimal topology for a piezoelectric actuator under a static load. The project consists of two major parts: implementation of the control law into the commercial finite element code ABAQUS and studies in topology optimization. The first part gives a thorough derivation and explanation of the implementation of static feedback control and dynamic proportional and derivative control. The result is compared with results published in the literature. The second part examines the results of topology optimization with different geometries and constraints. Thus, this study develops fundamental understanding of advantageous shapes for optimal performing piezoelectric actuators.
