% Computes the friction for a reaction wheel. The wheels can have damping and Coulomb friction and stiction. If you call it with 'struct' it will return the default data structure. Type ReactionWheelFriction for a demo. -------------------------------------------------------------------------- Form: d = ReactionWheelFriction('struct'); f = ReactionWheelFriction( omega, d ) -------------------------------------------------------------------------- ------ Inputs ------ omega (:,:) Angular rate d (.) Data structure .cDampingRWA (n,1) Damping coefficient .torqueCoulombRWA (n,1) Coulomb friction torque .torqueStictionRWA (n,1) Stiction friction torque .alphaStictionRWA (n,1) Stiction velocity damping .betaSigmoid (1,1) .useSigmoid (1,1) Flag for sigmoid ------- Outputs ------- f (:,:) Friction --------------------------------------------------------------------------
