Abstract

This paper contains a presentation of the techniques needed to develop simulations for large scale systems which are composed of control systems, optics, and structures. A case study is presented which consists of a generic, controlled specraft whose purpose is to maintain a precise line-of-sight (LOS) in the presence of disturbances and structural deformations. The spacecraft model consists of a six degree-of-freedom (DOF) rigid body with superimposed small structural deformaüons obtained from high-order finite element model. The optical system consists of a telescope with a controlled Fast Steering Mirror (FSM) for maintaining an accurate line-of-sight. Reaction wheels and an Inertial Measurement Unit (IMU) are used for spacecraft attitude control. Disturbances consist of onboard payload motions, sensor noises and reation wheel imbalance. Results of the simulation are shown.
