BDE-Motion Control

The most recent class of control techniques to be used are collectively referred to as adaptive control.

Simple closed-loop control has been used for decades to perform machine tool contouring.

A technique called dual-loop control is sometimes used to compensate for instabilities caused by backlash.

The design of a closed-loop positioning system demands that special trade-offs be made in loop gain and bandwidth to ensure stability.

Self-contained machines such as fryers for fast-food restaurants, cook-and-hold ovens, and bakery equipment usually employ a simple automatic controller.

In some factories, computers called cell controllers provide coordination among individual workstations and computer-controlled machines.

Simple control tasks can be candidates for pneumatic, electropneumatic, and hybrid pneumatic controls.

BASICS OF CABLE CARRIER SYSTEMS A cable carrier guides and protects automated cables and hoses on all types of industrial machinery and equipment.

Board-level motion controllers typically contain one or more circuit boards mounted in a card-rack chassis.

A number of commercially available board-level computers are targeted specifically at servocontrol.

Manufacturers have also developed special-purpose ICs that handle tasks needed to implement both closed-loop motion control and motor speed control.

Motion control today takes place under the guidance of computers, solid-state logic, or pneumatic sequencers.

A number of positioning components are commonly employed in industrial closed-loop systems today.
