DtTurretSlewController Class Reference

DtTurretSlewController is a controller that has those capabilities common to all controllers that manipulate turret actuators.

End User Description: Specific turret controllers (e.g. scan controller), extend this controller, and turret actuators expect to be controlled by a class derived from this one. Max-slew-rate and the turret part type to control are parameters. Generated values (-1. to 1.) cause the turret to slew by some (actuator-defined proportion of max-slew-rate). This controller cheats and assumes that function is linear. Another could choose to add a feedback loop and increase/decrease output based on the actual slew rate occurring.

Developer Description: Creates the ports needed to control a turret actuator and manages the various parameters and state needed.

Uses Descriptor Type: DtComponentDescriptor

Member Function Documentation

virtual bool DtTurretSlewController::init ( )

overridevirtual

Calls setRadio()

Reimplemented from DtControllerComponent.

virtual const char* DtTurretSlewController::type ( ) const

overridepure virtual

Returns a string identifies the class type of component. Type values are defined in compTypes.h. DtSimComponent creation functions are registered with the DtSimComponentFactory using the type values as the key. Warning: this function should always return the same pointer and it should be valid forever. This means the data should be static.

Returns

One of the type strings defined in compTypes.h

Implements DtControllerComponent.

Implemented in DtTurretAimController, DtTurretReturnToHeadingController, and DtGroundJoyTurretController.

virtual void DtTurretSlewController::tick ( )

overridevirtual

Deriving controllers should call this FIRST in their tick to ensure that parameter values have been looked up from the actuator (unless you don't need those values.)

Reimplemented from DtSimComponent.

Reimplemented in DtTurretAimController, and DtTurretReturnToHeadingController.

virtual double DtTurretSlewController::approximateSlew ( double  angle )

virtual

We use this to approximate the correct slew amount for a given dA. Returns the slew angle desired, divided by the product of maxSlewRate() and dT. If the value returned is outside the range -1.0 to 1.0 it is constrained by the slew port itself.

virtual void DtTurretSlewController::setMaxSlewRate ( DtReal  maxSlewRate )

virtual

virtual DtReal DtTurretSlewController::maxSlewRate ( ) const

virtual

virtual DtArtPartType DtTurretSlewController::turretToControl ( ) const

virtual

Gets the turret in this system from the PSR.

virtual double DtTurretSlewController::turretBodyRotation ( ) const

virtual

Returns the current rotation of the turret (specified by turretToControl()) in the reference from of the entity body.

virtual bool DtTurretSlewController::createSlewPort ( )

virtual

These are called by createPorts to create the ports used to communicate with the actuator.

virtual DtConstrainedAnalogOutputPort* DtTurretSlewController::slewPort ( )

virtual

The slew port is constrained to -1. + 1. Positive values should slew counterclockwise, negative values clockwise (looking down the axis. Since our body coordinate systen is z-down, a positive value would rotate clockwise if looking down on the object, for example a turret on a tank).

virtual bool DtTurretSlewController::createPorts ( )

overrideprotectedvirtual

Called by init to create the ports.

Reimplemented from DtSimComponent.

Reimplemented in DtTurretAimController.

virtual void DtTurretSlewController::lookupAndCacheProcessSR ( )

protectedvirtual

This function looks up a process state repository in the process state repository manager by name, and caches a pointer to it in myProcessState. The name (if it exists) is given in the component descriptor (DtComponentDescriptor::processStateRepositoryName). If the name does not exist, it uses the appropriate default name defined in psrTypes.h. Another component is responsible for creating and destroying the process state repository.

const DtTurretSlewController& DtTurretSlewController::operator= ( const DtTurretSlewController &  orig )

protected

assignment operator; not implemented

DtVrfTurretedBalGunPSR* DtTurretSlewController::myProcessState

protected

Pointer to a process state repository used to store state data associated with this component. This process state repository is shared with other components. Another component is responsible for creating and destroying the process state repository. This state is saved and restored as part of a scenario (or checkpoint).
