A smart sensor can be defined as a device that measures the environment, converts the input into a signal, and interfaces with a well-programmed controller.1 The controller then automatically calculates and delivers a control signal to an actuator that determines a quantity of output from the actuator.2 If the actuator is commanded to maintain physiologic homeostasis, then the system is known a...

To overcome the limitations of the independent stacked hybrid actuator with multiple sensors, a new hybrid linear actuator combines the advantages of both technologies: piezo actuator for extremely high accuracy and motorized stage for long travel ranges. A hybrid linear actuator prototype is developed for testing in our satellite tracking antenna pointing control system. For the maximum absolu...

The main objective of this study is to reduce optimal vibration suppression of Timoshenko beam under non-periodic step and impulse inputs. Cantilever beam was modeled by Timoshenko theory and finite element numerical method. Stiffness (K), mass (M), and damping (C) matrices are extracted. Then, in order to control structure vibration, piezoelectric patches were used due to simultaneous dual beh...
