Abstract :
Microvibrations at frequencies between 1 and 1000 Hz generated by on-board equipment can propagate through a satellite´s structure and hence significantly reduce the performance of sensitive payloads. This paper describes a Lagrange-Rayleigh-Ritz method for developing models suitable for the design of active control schemes. Here loop transfer recovery (LTR) based controller design methods are employed with this modeling strategy
