Abstract :
This paper describes an approach to the cancellation of multiple tones in a multiple-input, multiple-output linear system that requires no prior modeling information and recovers from sensor and actuator faults. Tests were performed on the Advanced Space Structures Technology Experiments (ASTREX) test facility located at the Air Force Phillips Laboratory, Kirkland Air Force Base. Over 30 dB reduction in three tonal frequencies was obtained in two line-of-sight sensors using six truss bending actuators, including multiple simulated actuator faults
