class RWConfigMessage;Description
Message used to define the individual RW (reaction wheel) configuration data message. This will store all of the configuration for a particular configuration of a single reaction wheel.
Properties
| Declared | Description |
|---|---|
| AOmega | Parameter used in coupled jitter back substitution. |
| BetaStatic | Stribeck friction coefficient. For stribeck friction to be activated,user must change this variable to a positive non-zero number. |
| BOmega | Parameter used in coupled jitter back substitution. |
| COmega | Parameter used in coupled jitter back substitution. |
| CurrentTorque | Current motor torque. |
| D | Wheel center of mass offset from wheel frame origin. |
| DynamicImbalance | Dynamic imbalance. |
| FrictionCoulomb | Coulomb friction torque magnitude. |
| FrictionStatic | Static friction torque magnitude. |
| FrictionStribeck | Boolean to determine if Stribeck friction model is used or not,0 is non-Stribeck, 1 is Stribeck/ Parameter is set internally. |
| FrictionTorque | Friction torque, this is a computed value, don’t set it directly. |
| FrictionViscous | Viscous friction coefficient. |
| Inertia_B | RW inertia about point Wc in B frame components. Also knownas ‘IRWPntWc_B’. This is the inertia of the center of massof the RW in the body frame. |
| InertiaPrime_B | RW inertia B-frame derivative. Also known as ‘IPrimeRWPntWc_B’, whichis the inertia rate of change of the center of mass of the RW in thebody frame. |
| J13 | X-Z inertia of wheel about wheel center in wheel frame (imbalance). |
| Jg | GgHat axis rotor moment of inertia. |
| Js | Spin axis gsHat rotor moment of inertia. |
| Jt | GtHat axis rotor moment of inertia. |
| MaxMomentum | Maximum RW wheel momentum in Nms. |
| MaxTorque | Max torque, negative value turns off saturating the wheel. |
| MinTorque | Min torque of the wheel. |
| Omega | Wheel speed. |
| OmegaBefore | Wheel speed one time step before. |
| OmegaLimitCycle | Wheel speed that avoids limit cycle with friction. |
| OmegaMax | Max wheel speed, negative values turn off wheel saturation. |
| Position_CB_B | Position of the reaction wheel center of mass Wc relative to Bin B-frame components. Also known as ‘r_WcB_B’. |
| PositionPrime_CB_B | B-frame derivative of r_WcB_B. Also known as ‘rPrime_WcB_B’. |
| PositionTilde_CB_B | Tilde matrix of r_WcB_B. This is the skew symmetric matrix of theposition of the reaction wheel center of mass Wc relative. This isalso known as ‘RTildeWcB_B’. |
| RWStatus | Type of operating model. |
| StaticImbalance | Static imbalance. |
| Theta | Wheel angle. |
| W2Hat_B | Current torque axis unit vector in body frame. |
| W2Hat0_B | Initial torque axis unit vector in body frame. |
| W3Hat_B | Current gimbal axis unit vector in body frame. |
| W3Hat0_B | Initial gimbal axis unit vector in body frame. |
| WheelMass | Reaction wheel rotor mass. |
| WheelModelType | Type of imbalance model to use. |
| WheelPosition_B | Position vector of the RW relative to the spacecraft body frame. Thisis the ‘RWB_B’ parameter. |
| WheelSpinAxis_B | Spin axis unit vector gsHat in B-frame components. |
