Terpstra, A.P. van Woerkom, P.T.L.M. van den Dam, R.F. Institution National Aerospace Laboratory NLR Date 1982-10-15 Abstract This document presents an approach to sampled data, on-board estimation and control of the attitude motion of manoeuvring spacecraft. Algorithms which are developed include: a - model following control of attitude manoeuvres b - estimation of spacecraft state (attitude, angular velocity, disturbance torque) c - optical-inertial attitude determination, with estimation of gyro parameters (drift rate bias, scale factor error). The algorithms were validated in single-axis software simulations of an attitude control system of the type as used in the Infra Red Astronomical Satellite (IRAS). The considered control system comprises a strapdown rate-integrating gyro and a slit-type star sensor for optical-inertial attitude sensing, a reaction wheel actuator, and a digital on-board computer. The truth models for simulation of the hardware components are discussed. The estimation and control algorithms are described, design trade-offs are discussed, and simulation results are presented. In Part II a general overview of the tasks of the simulation program is presented, and program design aspects are discussed. Each module is then described separately and flow charts are given. Finally, implementation aspects specific to the computer used, as well as some execution characteristics are briefly discussed.
