Abstract :
The paper addressed the problem of approximate linearization of a nonlinear control system by state feedback or dynamic feedback. The main result proved is that if the first k d-relative degrees are equal to each other, then the input-output response of a nonlinear control system can be linearized to degree k. Any system having linear d-relative degree can be linearized to any degree by dynamic feedbacks. One example of signal tracking using dynamic feedback linearization method to improve the performance is also given
