edu.wpi.first.wpilibj2.command.PIDCommand

All Implemented Interfaces:: Sendable, Command

public class PIDCommand
extends CommandBase

A command that controls an output with a PIDController. Runs forever by default - to add exit conditions and/or other behavior, subclass this class. The controller calculation and output are performed synchronously in the command's execute() method.

Constructor Details
- PIDCommand
  
  public PIDCommand(PIDController controller, DoubleSupplier measurementSource, DoubleSupplier setpointSource, DoubleConsumer useOutput, Subsystem... requirements)
  
  Creates a new PIDCommand, which controls the given output with a PIDController.
  
  Parameters:
  
  controller - the controller that controls the output.
  
  measurementSource - the measurement of the process variable
  
  setpointSource - the controller's setpoint
  
  useOutput - the controller's output
  
  requirements - the subsystems required by this command
- PIDCommand
  
  public PIDCommand(PIDController controller, DoubleSupplier measurementSource, double setpoint, DoubleConsumer useOutput, Subsystem... requirements)
  
  Creates a new PIDCommand, which controls the given output with a PIDController.
  
  Parameters:
  
  controller - the controller that controls the output.
  
  measurementSource - the measurement of the process variable
  
  setpoint - the controller's setpoint
  
  useOutput - the controller's output
  
  requirements - the subsystems required by this command
Method Details
- initialize
  
  public void initialize()
  
  Description copied from interface: Command
  
  The initial subroutine of a command. Called once when the command is initially scheduled.
- execute
  
  public void execute()
  
  Description copied from interface: Command
  
  The main body of a command. Called repeatedly while the command is scheduled.
- end
  
  public void end(boolean interrupted)
  
  Description copied from interface: Command
  
  The action to take when the command ends. Called when either the command finishes normally, or when it interrupted/canceled.
  Do not schedule commands here that share requirements with this command. Use Command.andThen(Command...) instead.
  
  Parameters:
  
  interrupted - whether the command was interrupted/canceled
- getController
  
  public PIDController getController()
  
  Returns the PIDController used by the command.
  
  Returns:
  
  The PIDController
