Abstract

The on-orbit system identification and vibration suppression performance of the advanced controls technology experiment (ACTEX) is discussed. The flight structure consists of an active tripod structure with piezoceramic actuators and sensors embedded within the composite layout of the three legs. The flight electronics contain a number of pre-programmed experiments as well as the command/control and signal processing electronics. Both system identification and vibration suppression experiments are contained within the pre-programmed set of experiments. The performance of the system in identification and control over its first year in space is discussed
