Reaction wheels (RWs) used for attitude control of space vehicle systems usually encounter with undesired wide band noises. These noises which significantly affect the performance of regulator controller must tune the review or review rate of RWs. According to wide frequency band of noises in RWs the common approaches of noise cancellation cannot conveniently reduce the effects of the noise. Th...

This paper presents the development of a dynamic Active Noise Control (ANC) algorithm aimed towards reducing broadband noise inside helmet earcups fighter aircraft pilot helmet. The ANC involves Variable Step-Size Griffiths (VSSG) FxLMS to attenuate entering directly through helmet, LMS based adaptive canceller microphone, and energy detectors for failure protection optimized battery power usag...
