Abstract : HUSETTS INST OF TECH LEXINGTON LINCOLN LABAttitude Control Dynamics for LES-8/9.Technical note,Smith,Norval P. ;Brockett,Roger W. ;TN-1973-27F19628-73-C-0002AF-649LESDTR-73-232(*satellite attitude, *attitude control systems), equations of motion, mathematical modelsThe equations of motion for a rigid body with a gimbaled momentum wheel and gyro are given here together with their derivation. The authors also give the linearized version of these equations together with the equations for the attitude control system. The linearized system is expressed in terms of transfer functions relating thruster torque, gimbal motor and wheel motor inputs to small angle responses. (Author)
