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

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