Extended Servo Applications — The Role of the Microcomputer

The present trend in control systems is to extend the application possibilities of existing fluid power technology by using the intelligence, flexibility and speed that the micro-computers are offering in a constantly improving cost efficient manner. Several years ago it was pointed out that the micro-computer’s role in closed loop control would involve the following areas:

• -Closing the loop
• - Pre-loop processing
• - Peripheral processing
• - Adaptive control
• - “Smart” redundancy
• - Improved time-optional control

By example, this paper* will show how the first three of the six above areas were involved in Extending Servo Applications.
