Yeah. Articles like this one is why I started following HN religiously. I would understand "analog computer" as some form of a proportional controller - like PID, but with ID terms set to 0:

The sensor must be able to somehow measure how fast the target is moving relatively to the center of the sensor area. The proportional controller then sets the fins in a slightly exaggerated fashion. |
