Abstract

Inertial navigation sensors are widely used in space missions, orbit determination, and vehicle's navigation, guidance and control sections. These sensitive sensors can be affected by extreme vibration excitations; which must be protected from high level excitations with addition to accuracy improvement. Although Inertial Measurement Unit (IMU) single-degree-of-freedom (SDOF) model is the simplest model to study vibration isolation but a fortune of information may be obtained about isolation characteristics, while two-degree-of-freedom (2DOF) IMU model is closer to real model. The new developed Transfer Matrix Method for Multibody Systems (MSTMM) compared with ordinary dynamic methods has modeling flexibility, low order system matrix, and high computational efficiency, without need of establishing the system's global dynamic equations. It has the merit of merging classical control techniques without needing especial treatments for different dynamics models. Main objectives are studying of flexibility effects in isolation design using MSTMM and transmissibility study, and then formulating a relationship with different control strategies. Simulated and experimental results indicated an availability of merging that allow wider developed control applications using MSTMM for more complex systems' models. Dilatation in studying controlled systems using MSTMM provides a possibility for incoming control applications because of the efficient dealing with the increased complexities of multi-rigid-flexible-body problems.
