“Control system” means something a bit more specific than “whatever it is that causes the behavior of the system”. A control system has an input, an output, and a set point. It varies the output based on the difference (error) between the input and the desired set point (sometimes it has terms for the derivative or for the accumulation of the error, but not always). In practice this means that it is hard to move the output away from the set point since the control system will respond by pushing in the opposite direction.
In the context in which I have been seeing the statement that “the” control system moves a certain behavior, there is nothing but the claim that the control system does exactly do what it is claimed to do. No precise explanation. No precise prediction (sure, the claim is that the output moves towards the set point, but nothing about the time dimension). If anything, the term is always used to “explain” behavior ex-post.
