What a control loop closes
A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline.
The short version
A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline.
What happened
A control loop is a standing subject on the Robotics desk. A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline. The page keeps that sentence so a trend headline does not have to. A reader who arrived from a wire line can use the sources instead of the headline. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.Futureweb.
The record
The record for A control loop is NIST SP 800-160 on trustworthy systems, applied to a loop that has a deadline. A model that answers in a second is not in the loop if the loop must finish in a millisecond. Futureweb files the distinction here and leaves the source documents in the box, linked, rather than pasted. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed. The sources for A control loop are listed below and are the place a quote should be verified.
The document
The document to open for A control loop is NIST SP 800-160 on trustworthy systems, applied to a loop that has a deadline. A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline. A second page that repeats a vendor adjective without this document has not added a fact. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.
Why it matters on this desk
On the Robotics desk, A control loop matters because a reader has a check they can perform. A reader asks for the deadline and for what the machine does when the deadline is missed. The desk files the check. It does not file a slogan in place of the check. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed. The sources for A control loop are listed below and are the place a quote should be verified.Robotics.
What a reader can check
A reader asks for the deadline and for what the machine does when the deadline is missed. That is the check for A control loop. A model that answers in a second is not in the loop if the loop must finish in a millisecond. If the check cannot be done from the documents, the page is ahead of the record and should say so. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.Hardware.
Where accounts differ
Accounts of A control loop differ when one source states A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline. and another skips the condition. A model that answers in a second is not in the loop if the loop must finish in a millisecond. This page does not average those accounts into a third claim neither document made. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.
What to watch next
What to watch for A control loop is a revision of NIST SP 800-160 on trustworthy systems, applied to a loop that has a deadline, or a shipping change that makes A model that answers in a second is not in the loop if the loop must finish in a millisecond. either more common or impossible. The URL stays. The text changes when the document changes. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.memory safety in the release notes.
What would change this page
This page on A control loop would change if NIST SP 800-160 on trustworthy systems, applied to a loop that has a deadline redefined the term, or if a measurement showed A model that answers in a second is not in the loop if the loop must finish in a millisecond. was the wrong failure. Until then the definition above is the one the desk will quote. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.the advisory.
What is still specific
What stays specific to A control loop is the pair of facts in the opening: A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline. A reader asks for the deadline and for what the machine does when the deadline is missed. Neighboring pages on the Robotics desk answer a different question and should not be merged into this one. A control loop is named again here so the check is hard to miss: A reader asks for the deadline and for what the machine does when the deadline is missed.

Questions
What is A control loop?
A control loop reads a sensor, computes an error against a target, and commands an actuator. The loop is late if that cycle misses its deadline.
Which document defines A control loop?
Start with NIST SP 800-160 on trustworthy systems, applied to a loop that has a deadline. The sources box has the link.
What fails if A control loop is ignored?
A model that answers in a second is not in the loop if the loop must finish in a millisecond.
What can a reader check about A control loop?
A reader asks for the deadline and for what the machine does when the deadline is missed.
Does a wire headline replace this page on A control loop?
No. A wire line links to the outlet. This URL is Futureweb's definition.
