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.
