Robust Stabilization of Nonlinear Systems

The Optimization Problem

edit

Consider a non linear system whos dynamics are given by

 

where  , ,   and  ,   is Hurwitz stable and   is piecewise continuous in both   and  

We assume   is stabilizable so

  ,  

Assume that  

where   is the bounding parameter and  

The Data

edit

The matrices required to solve this problem are A, B, H

The LMI: Nonlinear Systems Robust Stabilization

edit

There exists scalars  ,  , and  , along with the matrices   such that the following optimization problem is feasible.

 

Conclusion:
