Detailed Description

Abstract parent class of all force components.

Forces acting on mirror are calculated as sum of 6 scalar forces (lateral forces in x,y and z direction and rotational forces (moments) around x,y and z axis). Individual actuators forces are summed in FinalForceComponent. Considered forces and demands are:

• AccelerationForceComponent
• ActiveOpticForceComponent (Z direction only)
• AzimuthForceComponent
• BalanceForceComponent
• ElevationForceComponent
• OffsetForceComponent
• StaticForceComponent
• ThermalForceComponent
• VelocityForceComponent

Force component can be enabled or disabled. When it is disabled, its contribution is scaled linearly to zero to prevent overstressing the mirror. Commanding of the enabled/disabled states and checking if the forces are enabled before being applied is performed in the ForceController class.

Member Function Documentation

disable()

void LSST::M1M3::SS::ForceComponent::disable

(

)

Disable the force component.

Starts to gradually scales force contribution to

getName()

const char * LSST::M1M3::SS::ForceComponent::getName ( )

inline

Returns force component name.

Returns

force component name

isActive()

bool LSST::M1M3::SS::ForceComponent::isActive ( )

inline

Returns true if the force compoment is active - shall be calculated.

Returns

true if the force component is either enabled or disabling (scaling back to 0)

isDisabling()

bool LSST::M1M3::SS::ForceComponent::isDisabling ( )

inline

Returns true if the force component is being disabled.

Returns

true if the force component is being disabled

isEnabled()

bool LSST::M1M3::SS::ForceComponent::isEnabled ( )

inline

Returns true if the force component is enabled.

Returns

true if the force component is enabled

Here is the caller graph for this function:

isInitialising()

bool LSST::M1M3::SS::ForceComponent::isInitialising ( )

inline

Returns true if the force component is being initialised.

Returns

true if the force component is being initialised

postEnableDisableActions()

virtual void LSST::M1M3::SS::ForceComponent::postEnableDisableActions ( )

pure virtual

Called after enable/disable changes.

Publish a state change for the component Pure virtual, needs to be overriden in children.

Here is the caller graph for this function:

postUpdateActions()

virtual void LSST::M1M3::SS::ForceComponent::postUpdateActions ( )

protectedpure virtual

Called after update to forces.

Check for forces that need to be clipped. Update SAL. Pure virtual, needs to be overriden in children.
