Let (A1, A2, B) be a triple of matrices representing two-order time-invariant linear systems, ẍ = A1ẋ+A2x+Bu. Using linearization process we study the controllability of second order linear systems. We obtain sufficient conditions for controllability and we analyze the kind of systems verifying these conditions. Key-Words: Two-order linear systems, linearization, feedback, controllability.

This paper deals with the use of extra freedom in the exact linearization technique. Firstly, the freedom in choosing the coordinate transformation and nonlinear state feedback for the exact linearization is clarified. Secondly, a controller design strategy for the transient behavior improvement in the presence of impulsive disturbances is shown. Finally, numerical and experimental examples exh...

This paper presents a methodology to solve maneuver regulation problems which is based on transverse feedback linearization. Necessary and sufficient conditions for the linearization of dynamics transverse to an embedded submanifold of the state space are presented. Various examples illustrate the main features of this framework.
