Abstract:   (4944 Views)
Development of the aerospace flight devices and as a result of this, the growing trend towards large flexible structures leading to control systems being designed in the presence of elastic behavior. Moreover most of the launch vehicle has been modeled as the beam without considering the payload. But actually, payload influences on the vibrational effects, that can lead to decrease the bending frequency in part of the flight time and as result, this reduces the stability of the control system obviously. For this purpose the payload is idealized as point mass and a non-linear dynamic model of system is simulated by eight DOF. In this paper, a control strategy based on 'model reference adaptive approach' is applied to appraise a single vibration mode of a flexible launch vehicle with heavy payload. This approach makes of a model reference adaptive lattice notch filter which has been implemented on the flexible systems in the case of recursive form for a launching system in the presence of the heavy payload
Keywords: Flexible launch vehicle, heavy payload, Vibrational frequency identification, lattice notch filter
