Since this is liveblogging a course, I wonder if it would also be possible for you to post the exercises? Sure I could just pick up the control theory book on my desk and do exercises in there, but since I'm reading these notes, it would help to have the exercises be a bit more in sync.

One important concept that does not immediately follow from homeostatic considerations is dynamic equilibrium. While it is necessary to maintain fixed setpoints as a matter of life or death, life processes involve time variation, where certain temporal trajectories are viable while others are not.

If G depends on the state only, then F = identity guarantees constant reguland? What am I missing here? :)

F is the system dynamics where the appearance of a disturbance probably can’t be assumed to be controlled. Typically F also has an input argument (the thing that can be controlled), and that is what is doing the regulation (rejecting the disturbance).

Thanks. There probably should be a time dependency in G as well? Eg if the reguland is a deviation from the planned trajectory, then it will depend on time.
