Higher-Order Approximate Feedback Linearization About a Manifold for Multiinput Systems
We consider the problem of approximately feedback linearizing a multi-input nonlinear system around the equilibrium manifold E while making the error terms be of highest order on E. Necessary and sufficient conditions are given for approximately feedback linearizing the system around E with error terms of order rho on E. A simple multi-input example is given to illustrate the higher order approximate feedback linearization procedure.
