Practical nonlinear control theory: on the frontier of linear control.

Nonlinear control theory is a difficult and complex field of study. Despite many advances being made over the last several decades, it is not routinely applied to industrial systems. It is more common for linear-type techniques to be adapted for nonlinear systems, but this approach typically lacks formal stability and performance guarantees. This seminar will provide some new perspectives on the use of nonlinear stability criteria for guaranteeing stability of nonlinear systems which have a "weakly nonlinear" structure. In particular it will be shown how some established tools from nonlinear stability theory may be exploited to obtain less conservative results. A practical example from flight control will be used to illustrate some of the results.
