Questions and Answers

What is the function of a feedback controller in a control system?

For continuously modulated control, a feedback controller is used to automatically control a process or operation by comparing the value or status of the process variable (PV) being controlled with the desired value or setpoint (SP), and applying the difference as a control signal to bring the process variable output of the plant to the same value as the setpoint.

Explain the purpose of a control system in simple terms.

A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops.

How were logic control systems historically implemented for industrial and commercial machinery?

Logic control systems for industrial and commercial machinery were historically implemented by interconnected electrical relays and cam timers using ladder logic.

What is the modern method for constructing logic control systems for industrial and commercial machinery?

<p>Today, most such systems are constructed with microcontrollers or more specialized programmable logic controllers (PLCs).</p> Signup and view all the answers

How do logic controllers cause machinery to start and stop various operations?

<p>Logic controllers may respond to switches and sensors and can cause the machinery to start and stop various operations through the use of actuators.</p> Signup and view all the answers

Flashcards

What is a feedback controller?

A feedback controller automatically adjusts a process or operation by comparing the actual value (process variable, PV) to the desired value (setpoint, SP), and then generates a control signal to bring the process variable closer to the setpoint.

What does a control system do?

A control system manages and regulates other devices or systems to make them behave as intended.

How were early logic control systems implemented?

Historically, logic control systems used a network of interconnected electrical relays and cam timers, with their connections represented using "ladder logic" diagrams.

How are modern logic control systems built?

Modern logic control systems are built with microcontrollers or programmable logic controllers (PLCs), offering more flexible and sophisticated control.

How do logic controllers control machinery?

Logic controllers respond to signals from switches and sensors, and send out signals to actuators that make machinery start or stop various operations.
