The Airborne Laser (ABL) system has extremely tight jitter requirements. Acoustic disturbances, such as those caused by the pressure recovery system of the high power laser, are a significant jitter source. Several technologies may be appropriate for reducing the acoustically induced jitter. The first choice for mitigation will be passive approaches, such(More)
Numerous vibration control techniques, employing both passive and active methods, have been developed and tested over the last several decades. Some of these techniques are in widespread use, while others have rarely or never left the laboratory. This paper considers the value that vibration damping and control of aircraft fins and appendage structures can(More)
Future space systems will require high robustness of the control system as well as high performance because of their two major features: lightly damped structural dynamics ; and nonlinear inertia properties induced by the large motion of articulating sensor heads and antennas. Effective robust control design techniques are needed to satisfy the performance(More)
