- Parameters
RW – reaction wheel configuration message
- Returns
- addToSpacecraft(modelTag, rwStateEffector, sc)[source]¶
This function should be called after all RW devices are created with createRW() It creates the C-class container for the array of RW devices, and attaches this container to the spacecraft object
:param : :type : param modelTag: string with the model tag :param : :type : param rwStateEffector: :param : :type : param sc: spacecraft object
- create(rwType, gsHat_B, **kwargs)[source]¶
This function is called to setup a RW device in python, and adds it to the RW factory list rwList{}. The function returns a copy of the device that can be changed if needed. The first 2 arguments are required, the remaining arguments are optional with:
- Parameters
rwType (string) – RW manufacturing name.
gsHat_B (list) – Spin axis unit vector gsHat in B-frame components
kwargs – Omega : initial RW speed in RPM Omega_max : maximum RW speed in RPM rWB_B : 3x1 list of RW center of mass position coordinates RWModel : RW model type such as BalancedWheels, JitterSimple and JitterFullyCoupled useRWfriction : BOOL to turn on RW internal wheel friction useMinTorque : BOOL to clip any torque below a minimum torque value useMaxTorque : BOOL to clip any torque value above a maximum torque value u_max: double with the maximum RW motor torque maxMomentum : maximum RW wheel momentum in Nms. This is a required variable for some wheels. label : string with the unique device name, must be 5 characters or less fCoulomb: double for the Coulomb friction torque model fStatic: double for Static friction torque magnitude betaStatic: double for Stribeck friction coefficient, positive turns Stribeck friction on, negative turns this friction off cViscous: double for Viscous friction coefficient
- Returns
RWConfigSimMsg – A handle to the RW configuration message
- Return type
message structure
- custom(RW)[source]¶
Creates an empty reaction wheel configuration message. This assumes the user provided the RW maximum speed and maximum angular momentum information.
- Parameters
RW – reaction wheel configuration message
- Returns
