Detailed Description

Request PID to target velocity with duty cycle feedforward.

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

Constructor & Destructor Documentation

◆ VelocityDutyCycle() [1/2]

ctre::phoenixpro::controls::VelocityDutyCycle::VelocityDutyCycle	(	units::angular_velocity::turns_per_second_t	Velocity,
		bool	EnableFOC,
		units::dimensionless::scalar_t	FeedForward,
		int	Slot,
		bool	OverrideBrakeDurNeutral
	)

inline

Request PID to target velocity with duty cycle feedforward.

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

Parameters

Velocity	Velocity to drive toward in rotations per second.
EnableFOC	Set to true to use FOC commutation, 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.
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.

◆ VelocityDutyCycle() [2/2]

ctre::phoenixpro::controls::VelocityDutyCycle::VelocityDutyCycle ( units::angular_velocity::turns_per_second_t Velocity )

inline

Request PID to target velocity with duty cycle feedforward.

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

Parameters

Velocity Velocity to drive toward in rotations per second.

Member Function Documentation

◆ ForceApplyConfigs()

void ctre::phoenixpro::controls::VelocityDutyCycle::ForceApplyConfigs ( )

inline

Forces configs to be applied the next time this is used in a setControl.

This is not necessary in the majority of cases, because Phoenix will make sure configs are properly set when they are not already set

◆ ToString()

std::string ctre::phoenixpro::controls::VelocityDutyCycle::ToString ( ) const

inlinevirtual

Returns a string representation of the object.

Returns: a string representation of the object.

Implements ctre::phoenixpro::controls::ControlRequest.

◆ WithEnableFOC()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithEnableFOC ( bool newEnableFOC )

inline

Modifies this Control Request's EnableFOC parameter and returns itself for method-chaining and easier to use request API.

Parameters

newEnableFOC Parameter to modify

Returns: Itself

◆ WithFeedForward()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithFeedForward ( units::dimensionless::scalar_t newFeedForward )

inline

Modifies this Control Request's FeedForward parameter and returns itself for method-chaining and easier to use request API.

Parameters

newFeedForward Parameter to modify

Returns: Itself

◆ WithOverrideBrakeDurNeutral()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithOverrideBrakeDurNeutral ( bool newOverrideBrakeDurNeutral )

inline

Modifies this Control Request's OverrideBrakeDurNeutral parameter and returns itself for method-chaining and easier to use request API.

Parameters

newOverrideBrakeDurNeutral Parameter to modify

Returns: Itself

◆ WithSlot()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithSlot ( int newSlot )

inline

Modifies this Control Request's Slot parameter and returns itself for method-chaining and easier to use request API.

Parameters

newSlot Parameter to modify

Returns: Itself

◆ WithUpdateFreqHz()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithUpdateFreqHz ( units::frequency::hertz_t newUpdateFreqHz )

inline

Sets the period at which this control will update at.

This is designated in Hertz, with a minimum of 20 Hz (every 50 ms) and a maximum of 1000 Hz (every 1 ms).

If this field is set to 0 Hz, the control request will be sent immediately as a one-shot frame. This may be useful for advanced applications that require outputs to be synchronized with data acquisition. In this case, we recommend not exceeding 50 ms between control calls.

Parameters

newUpdateFreqHz Parameter to modify

Returns: Itself

◆ WithVelocity()

VelocityDutyCycle & ctre::phoenixpro::controls::VelocityDutyCycle::WithVelocity ( units::angular_velocity::turns_per_second_t newVelocity )

inline

Modifies this Control Request's Velocity parameter and returns itself for method-chaining and easier to use request API.

Parameters

newVelocity Parameter to modify

Returns: Itself

The timeout when sending configs associated with this control.

◆ EnableFOC

bool ctre::phoenixpro::controls::VelocityDutyCycle::EnableFOC

Set to true to use FOC commutation, 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.

◆ FeedForward

units::dimensionless::scalar_t ctre::phoenixpro::controls::VelocityDutyCycle::FeedForward

Feedforward to apply in fractional units between -1 and +1.

◆ OverrideBrakeDurNeutral

bool ctre::phoenixpro::controls::VelocityDutyCycle::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.

◆ Slot

int ctre::phoenixpro::controls::VelocityDutyCycle::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].

◆ UpdateFreqHz

units::frequency::hertz_t ctre::phoenixpro::controls::VelocityDutyCycle::UpdateFreqHz {100_Hz}

The period at which this control will update at.

This is designated in Hertz, with a minimum of 20 Hz (every 50 ms) and a maximum of 1000 Hz (every 1 ms).

If this field is set to 0 Hz, the control request will be sent immediately as a one-shot frame. This may be useful for advanced applications that require outputs to be synchronized with data acquisition. In this case, we recommend not exceeding 50 ms between control calls.

◆ Velocity

units::angular_velocity::turns_per_second_t ctre::phoenixpro::controls::VelocityDutyCycle::Velocity

Velocity to drive toward in rotations per second.
