Abstract

The purpose of this paper is to verify the effectiveness of self-sensing piezoelectric actuation using an affordable micro-controller. In recent years, space structural systems have been required high precision and high functionality for advanced space missions. Vibration control is one of important issues to realize high mirror accuracy of antennas for a high-resolution observation and a high-capacity communication. Generally, active vibration control needs not only actuators and sensors, but also AD/DA converters and highly advanced arithmetic processing. However, it is difficult to mount complex and heavy devices on satellites. A compact and modulized unit for vibration control is necessary. Then, this study focused on an affordable micro-controller that is small, low power consumption and easily-available. And self-sensing actuation was chosen as the vibration control technique to reduce in size and weight of the control system. Numerical simulations and experiments to damp free decay vibration and harmonic vibration of a smart cantilever were demonstrated, and show that the presented approach is very useful for realizing the active vibration control unit.
