Information and Control Systems

This is a page for the use of Information Theory as an aid to understanding and analysing control systems. Information Theory is used in the sense defined by Shannon (1947). The control systems of interest are of the kinds considered in Perceptual Control Theory.

There are (or will be) several different notes, most of which can be read independently.

On the concept of probability.
On uncertainty and information
On signal bandwidth and measurement precision
On the concept of control
On thethermodynamic necessity of Perceptual Control
On uncertainty and processing delays in control
On uncertainty in perception.
On the effectiveness of control
On the limits of correlation between perceptual signal and disturbance signal
