Output stabilization of square nonlinear systems

Robert Mahony, Iven Mareels, Georges Bastin, Guy Campion
1997 Automatica  
This paper considers the problem of designing static-state feedback laws for output regulation of square affine nonlinear systems.  ...  In the case where the input-output decoupling matrix is rankdegenerate, it is shown that a static-state control law for output regulation can be constructed as long as the system can be input-output decoupled  ...  For a general affine nonlinear system of the form (1) it is unlikely that a singularity will occur exactly on the zero-output-level set.  ...
