-
- Dennis Delprato and Bill Powers:
-
- I suppose here's another misunderstanding concerning control systems that
- we might want to add to our library.
-
- In discussion the application of control system models to understanding
- "motor control" with a physiological psychologist, he was arguing that the
- ability to predict meant that feedforward was taking place. The example he
- used was predicting the movement that an object would take and using that
- knowledge for tracking (like how it's easier to point to a the end of a
- swinging pendulum than to a fly caught in the shower stall with you).
-
- I don't think I did a very good job at trying to explain how tracking
- patterns can be seen as controlling a higher-level perceptual variable.
- Perhaps someone can help could help me out with this. It is also related,
- I believe, to the discussion between Taylor and Powers concerning what a
- control systems has to be able to "predict" in order to maintain good
- control.--Gary
