On Robust Approximate Feedback Linearization: A Nonlinear Control Approach

In this letter, we consider a problem of global stabilization of a class of approximately feedback linearized systems. We propose a new nonlinear control approach which includes a nonlinear controller and a Lyapunov-based design method. Our new nonlinear control approach broadens the class of systems under consideration over the existing results. key words: approximate feedback linearization, global exponential stabilization, nonlinear approach
