Finding maximum linear subsystems of nonlinear systems with outputs
The focus of this paper is to find the maximum input-output linearized subsystem. Necessary and sufficient conditions are presented under which there exist a static state feedback and a coordinate change to input-output linearize the system so that the linear subsystem has the largest dimension. A systematic method is also developed to compute the desired feedback and coordinate change.
