Double Loop Control Theory by William T Powers

Double loop version of IM-8908 Based on 1990 SDR Article. Control systems act to make their own input match internal standards or reference signals. Competent control systems create illusions of stimulus response causality. Stimulus-response theory can approximate the relationship between disturbance and action, but it can't predict the consequences of behavior. These consequences are maintained despite disturbances.

Here we introduce Bill Powers concept of hierarchy of control. We start with the single control loop with an internal reference signal described in IM-8908
The [reference signal] for the Action System is now provided by a quantity called [intent quantity]
The [Intent quantity] stock is the output of a higher control system called the Intent System. This is the same structure as the lower order Action System with an Internal Environment.
The [perceptual signal] from the Action System provides the [disturbing quantity1] of the Internal Environment or Representation
Now Run the model and carefully study the results including the shapes of the [reference signal1] and the [disturbing quantity].
What other variables might you be able to turn into a stock to cope with the error mismatches? Think about perceptions and changes in mental models. Clone this model and try extending it
