Detailed Description

Request PID to target position with duty cycle feedforward.

This control mode will set the motor's position setpoint to the position specified by the user. In addition, it will apply an additional duty cycle as an arbitrary feedforward value.

◆ PositionDutyCycle()

ctre::phoenix6::controls::PositionDutyCycle::PositionDutyCycle	(	units::angle::turn_t	Position,
		units::angular_velocity::turns_per_second_t	Velocity = `0.0_tps`,

	)

inline

Request PID to target position with duty cycle feedforward.

This control mode will set the motor's position setpoint to the position specified by the user. In addition, it will apply an additional duty cycle as an arbitrary feedforward value.

Parameters

Position	Position to drive toward in rotations.
Velocity	Velocity to drive toward in rotations per second. This is typically used for motion profiles generated by the robot program.
EnableFOC	Set to true to use FOC commutation (requires Phoenix Pro), which increases peak power by ~15%. Set to false to use trapezoidal commutation.

FOC improves motor performance by leveraging torque (current) control. However, this may be inconvenient for applications that require specifying duty cycle or voltage. CTR-Electronics has developed a hybrid method that combines the performances gains of FOC while still allowing applications to provide duty cycle or voltage demand. This not to be confused with simple sinusoidal control or phase voltage control which lacks the performance gains.

Parameters

FeedForward	Feedforward to apply in fractional units between -1 and +1.
Slot	Select which gains are applied by selecting the slot. Use the configuration api to set the gain values for the selected slot before enabling this feature. Slot must be within [0,2].
OverrideBrakeDurNeutral	Set to true to static-brake the rotor when output is zero (or within deadband). Set to false to use the NeutralMode configuration setting (default). This flag exists to provide the fundamental behavior of this control when output is zero, which is to provide 0V to the motor.
LimitForwardMotion	Set to true to force forward limiting. This allows users to use other limit switch sensors connected to robot controller. This also allows use of active sensors that require external power.
LimitReverseMotion	Set to true to force reverse limiting. This allows users to use other limit switch sensors connected to robot controller. This also allows use of active sensors that require external power.
