Class MotionMagicVoltage

java.lang.Object
com.ctre.phoenixpro.controls.ControlRequest
com.ctre.phoenixpro.controls.MotionMagicVoltage
public class MotionMagicVoltage
extends ControlRequest
Requests Motion Magic® to target a final position using a motion profile. Users can optionally provide a voltage feedforward.

Motion Magic® produces a motion profile in real-time while attempting to honor the Cruise Velocity, Acceleration, and Jerk value specified via the Motion Magic® configuration values. Target position can be changed on-the-fly and Motion Magic® will do its best to adjust the profile. This control mode is voltage-based, so relevant closed-loop gains will use Volts for the numerator.

  • Field Details

    • Position

      public double Position
      Position to drive toward in rotations.

    • EnableFOC

      public boolean 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

      public double FeedForward
      Feedforward to apply in volts

    • Slot

      public int 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

      public boolean 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.

    • UpdateFreqHz

      public double UpdateFreqHz
      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.

    • configTimeout

      public double configTimeout
      The timeout when sending configs associated with this control
