Systems for Control

14.1 Introduction

The application of intelligent systems to control has far-reaching implications for manufacturing, robotics, and other areas of engineering. The control problem is closely allied with some of the other applications that have been discussed so far. For instance, a controller of manufacturing equipment will have as its aim the implementation of a manufacturing plan (see Chapter 13). It will need to interpret sensor data, recognize faults (see Chapter 11), and respond to them. Similarly, it will need to replan the manufacturing process in the event of breakdown or some other unexpected event, that is, to plan reactively (Chapter 13, Section 13.9). Indeed, some researchers treat automated control ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
