Some Notes About Nonlinear Morgan''s Problem
关于非线性Morgan问题的几点注记

For nonlinear Morgan's problem with one more inputs than outputs, Glumineau & Moog presented a constructive solution. This result was lately pointed out to be incorrect. In this paper, a modification of the Glumineau-Moog Theorem is given and a 10-dimensional system is also presented. This system has only one decoupling-feedback, and the essential orders of the decoupled closed-loop system are higher than those of the original system.
