Detailed Description

DtSimpleRotaryWingPilot is a controller that represents the autopilot aspects of a rotary-wing pilot.

End User Description: It sets the helicopter controls to achieve desired position, velocity, acceleration, and orientation. These values are provided over a set of input ports. The controller than uses these values to calculate the needed control inputs for the actuator, and sends these values on the output ports.

Uses Descriptor Type: DtRotaryWingPilotDescriptor

Calculate an upward desired velocity to maintain a safe distance from the terrain.

virtual void DtSimpleRotaryWingPilot::calculateControlAlignmentAngle	(	DtReal &	alignmentAngle,
		bool &	selector
	)		const

protectedvirtual

Calculate alignment based on controllers.

An angle and a specifier are returned. The angle value is the amount by which the helicopter should rotate about its z-axis to align with the desired heading. If the selector is True, the angle is valid. Uses local variables: myBodyToRef

virtual void DtSimpleRotaryWingPilot::calculateTargetAlignmentAngle	(	DtReal &	alignmentAngle,
		bool &	selector
	)		const

protectedvirtual

calculate alignment based on targets.

An angle and a specifier are returned. The angle is value the helicopter should rotate by about its z-axis to align with the target. If the selector is True, the angle is valid. Uses local variables: myBodyToRef

virtual bool DtSimpleRotaryWingPilot::createPorts ( )

protectedvirtual

Overridden to create rotary wing ports.

Reimplemented from DtRotaryWingPilotController.

static DtReal DtSimpleRotaryWingPilot::xyDistSquared	(	DtVector	a,
		DtVector	b
	)

static

Calculate the distance squared between the projections of the points onto the x-y plane.
