Controller Requirements for High-Precision Motion Applications
|
From Delta Tau Data Systems, Inc.
High-precision motion control applications put demands on a motion controller that many other applications do not. Many of the requirements are subtle, and not immediately obvious from data sheets. The designers of motion controllers must take special care to handle numeric issues, data rates, interpolation strategies, fast servo updates, and many other issues properly if they are to succeed in properly controlling a precision application. This paper surveys the key strategies required for success. Proper strategies for commanded trajectories are vital for the success of high-precision motion applications. This subject is ignored in virtually all academic controls courses, but it is at least as important as the servo algorithms used. Products & Services
CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.
