Control and filtering¶
-
lock¶
A simple lock which computes and applies the feedback to a given parameter using an error signal.
- Syntax
lock name errsig feedback_to gain accuracy disabled=false offset=0- Required
name: Name of newly created lock.errsig: An error signal parameter or an object capable of producing a real-type error signal. This is typically a demodulatedPowerDetectorinstance (or the name of the instance).feedback_to: A parameter of the model to apply the locks’ feedback signal to.gain: Control loop gain.accuracy: Threshold to decide whether the loop is locked.disabled: If true this lock will not run when the RunLocks() action is used. Explicitly specifying the name of the lock will override this setting, e.g. RunLocks(name).offset: An offset that is applied to the error signal before it is used.
