Is external control important for internal control?

In general, systems try to have internal control; most humans want to feel like they have control over their life. Some do this by aiming for external control: they want to fix how the environment behaves. Others do this by trying to find synergies with the environment. How can we formalize these different strategies for control, and which one functions the best? I will try to answer these questions in this paper. I will do so by generalizing the concept of coordination in hierarchical systems, introduced by Mesarovic. I will apply this to model different strategies for control: a global one used in the theory of controllability, or local ones based on neural networks and perceptual control theory.
