Detailed Description

Request a specified motor current (field oriented control).

This control request will drive the motor to the requested motor (stator) current value. This leverages field oriented control (FOC), which means greater peak power than what is documented. This scales to torque based on Motor's kT constant.

Constructor & Destructor Documentation

◆ TorqueCurrentFOC() [1/2]

ctre::phoenixpro::controls::TorqueCurrentFOC::TorqueCurrentFOC ( units::current::ampere_t  Output,
units::dimensionless::scalar_t  MaxAbsDutyCycle,
units::current::ampere_t  Deadband,
bool  OverrideCoastDurNeutral 
)
inline

Request a specified motor current (field oriented control).

This control request will drive the motor to the requested motor (stator) current value. This leverages field oriented control (FOC), which means greater peak power than what is documented. This scales to torque based on Motor's kT constant.

Parameters
OutputAmount of motor current in Amperes
MaxAbsDutyCycleThe maximum absolute motor output that can be applied, which effectively limits the velocity. For example, 0.50 means no more than 50% output in either direction. This is useful for preventing the motor from spinning to its terminal velocity when there is no external torque applied unto the rotor. Note this is absolute maximum, so the value should be between zero and one.
DeadbandDeadband in Amperes. If torque request is within deadband, the bridge output is neutral. If deadband is set to zero then there is effectively no deadband. Note if deadband is zero, a free spinning motor will spin for quite a while as the firmware attempts to hold the motor's bemf. If user expects motor to cease spinning quickly with a demand of zero, we recommend a deadband of one Ampere. This value will be converted to an integral value of amps.
OverrideCoastDurNeutralSet to true to coast 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 0A (zero torque).

◆ TorqueCurrentFOC() [2/2]

ctre::phoenixpro::controls::TorqueCurrentFOC::TorqueCurrentFOC ( units::current::ampere_t  Output)
inline

Request a specified motor current (field oriented control).

This control request will drive the motor to the requested motor (stator) current value. This leverages field oriented control (FOC), which means greater peak power than what is documented. This scales to torque based on Motor's kT constant.

Parameters
OutputAmount of motor current in Amperes

Member Function Documentation

◆ ForceApplyConfigs()

void ctre::phoenixpro::controls::TorqueCurrentFOC::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::TorqueCurrentFOC::ToString ( ) const
inlinevirtual

Returns a string representation of the object.

Returns
a string representation of the object.

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

◆ WithDeadband()

TorqueCurrentFOC & ctre::phoenixpro::controls::TorqueCurrentFOC::WithDeadband ( units::current::ampere_t  newDeadband)
inline

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

Parameters
newDeadbandParameter to modify
Returns
Itself

◆ WithMaxAbsDutyCycle()

TorqueCurrentFOC & ctre::phoenixpro::controls::TorqueCurrentFOC::WithMaxAbsDutyCycle ( units::dimensionless::scalar_t  newMaxAbsDutyCycle)
inline

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

Parameters
newMaxAbsDutyCycleParameter to modify
Returns
Itself

◆ WithOutput()

TorqueCurrentFOC & ctre::phoenixpro::controls::TorqueCurrentFOC::WithOutput ( units::current::ampere_t  newOutput)
inline

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

Parameters
newOutputParameter to modify
Returns
Itself

◆ WithOverrideCoastDurNeutral()

TorqueCurrentFOC & ctre::phoenixpro::controls::TorqueCurrentFOC::WithOverrideCoastDurNeutral ( bool  newOverrideCoastDurNeutral)
inline

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

Parameters
newOverrideCoastDurNeutralParameter to modify
Returns
Itself

◆ WithUpdateFreqHz()

TorqueCurrentFOC & ctre::phoenixpro::controls::TorqueCurrentFOC::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
newUpdateFreqHzParameter to modify
Returns
Itself

Member Data Documentation

◆ ConfigTimeout

units::time::second_t ctre::phoenixpro::controls::TorqueCurrentFOC::ConfigTimeout {0.1_s}

The timeout when sending configs associated with this control.

◆ Deadband

units::current::ampere_t ctre::phoenixpro::controls::TorqueCurrentFOC::Deadband

Deadband in Amperes.

If torque request is within deadband, the bridge output is neutral. If deadband is set to zero then there is effectively no deadband. Note if deadband is zero, a free spinning motor will spin for quite a while as the firmware attempts to hold the motor's bemf. If user expects motor to cease spinning quickly with a demand of zero, we recommend a deadband of one Ampere. This value will be converted to an integral value of amps.

◆ MaxAbsDutyCycle

units::dimensionless::scalar_t ctre::phoenixpro::controls::TorqueCurrentFOC::MaxAbsDutyCycle

The maximum absolute motor output that can be applied, which effectively limits the velocity.

For example, 0.50 means no more than 50% output in either direction. This is useful for preventing the motor from spinning to its terminal velocity when there is no external torque applied unto the rotor. Note this is absolute maximum, so the value should be between zero and one.

◆ Output

units::current::ampere_t ctre::phoenixpro::controls::TorqueCurrentFOC::Output

Amount of motor current in Amperes.

◆ OverrideCoastDurNeutral

bool ctre::phoenixpro::controls::TorqueCurrentFOC::OverrideCoastDurNeutral

Set to true to coast 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 0A (zero torque).

◆ UpdateFreqHz

units::frequency::hertz_t ctre::phoenixpro::controls::TorqueCurrentFOC::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.
