Tuning the controller
Here we consider the problem of choosing the amount of proportional action in the feedback loop, in following sections terminology and concepts used in linear control theory are used. It's of course obvious will not behave in a linearly way. But the concepts and design strategies of linear control theory can be translated to non-linear control theory.
One of the most usefull ways of investigating the behaviour of closed loop system is the investigation of the open loop system.
Stability
Tracking problem
We are mostly interested in the ability of the controlled system to follow a step input signal, for a linear system the steady state tracking error is:
