Module: ExtPulsedTorque

Executive Summary

Module: dynamicEffector Class used to provide a direct pulsed external torque on body The module PDF Description contains further information on this module’s function, how to run it, as well as testing.

Message Connection Descriptions

This module has no input or output messages. It is a pure dynamic effector.

class ExtPulsedTorque : public SysModel, public DynamicEffector 

#include <ExtPulsedTorque.h>

external pulsed torque module class

Public Functions

ExtPulsedTorque(): This is the constructor. It sets some default initializers that can be overriden by the user.

~ExtPulsedTorque(): The destructor. Nothing of note is performed here

void UpdateState(uint64_t CurrentSimNanos): Module update method

void linkInStates(DynParamManager &statesIn): link the states

void writeOutputMessages(uint64_t currentClock)

This module does not write any output messages.

Parameters:: currentClock – The current time used for time-stamping the message
Returns:: void

void readInputMessages()

This method is used to read the incoming message and set the associated buffer structure.

Returns:: void

void computeForceTorque(double integTime, double timeStep): This method is used to compute the RHS forces and torques. Note: the module can set any of these three vecors, or a subset. Regarding the external force, the matrix represnetations in the body (B) and inerial (N) frame components are treated as 2 separate vectors. Only set both if you mean to, as both vectors will be included.
