This may work well for telecommunications networks, and a bunch of others. There are problems with the explicit learning mode idea in a number of situations. It is sometimes very difficult or impossible to prescribe the operating conditions for certain units. A boiler for example starts out as one device and slowly degrades to another as it fouls. Controls which work great at first, may have a different effect after only a few days or weeks, and the change may be history dependent.
If you are running a system in which the responses to inputs remains relatively stable, even if there are several different stale states, your control will work fine. In other cases, the system dynamics will change in a matter which is somewhat but not precisely predictable, and the control will generate poor results. It will probably still work, just not as well.
If you are working on a system in which the dynamics are changed significantly, then you must be retained to rerun your characterization system. This might sound like job security, but it may also be viewed as a liability.

The main purpose of this approach is to design a system capable to work in the rapidly changing environment (If... (a new condition, then... ( a new control).
In my previous post:

We decompose input space on subspaces and define for each subspace a "good enough" control.
"The second phase is an open-loop control itself. During this phase

As soon as input point left the last solution input area, control system will define to which new control area an input belongs now and selects a new "good enough" control that corresponds to this new control area. This process of switching from one control to the other is continues. The more rapid and drastic changes are in the controlled system conditions, the better discussed approach is working.
