On control of voltage-actuated piezoelectric beam: A Krasovskii passivity-based approach

摘要

This paper presents a new passivity property for distributed piezoelectric devices with integrable port -variables. This novel passivity-based control approach is suited for dissipative systems. We present two new control methodologies by exploiting the integrability property of the port-variables. The derived controllers have a Proportional-Integral (PI) like structure and are shown to asymptotically stabilize the piezoelectric devices. Finally, simulation results are presented for both controllers for a PZT-4 piezoelec-tric device. (c) 2022 The Author(s). Published by Elsevier Ltd
