| Abstract: | A new intelligent member was designed and manufactured which can sense its location and force to adaptively control and improve performance of deployable structures. A design model was developed for a piezoelectric micro-placement actuator based on the actuation effect of piezoelectric materials. The composition of an intelligent active member and its operating mechanism are presented for aerospace adaptive-deployable structures. The new active member includes a piezoelectric actuator, a micro-placement sensor and a pressure sensor to measure the micro-placement and pressure. |
