%X In this paper,the globally asymptotical output- feedback stabilization problem is investigated for a class of non- linear systems with unmeasured states dependent growth and stable zero-dynamics.Because of the existence of zero-dynamics, a series of novel linear transformations are first defined to suc- cessfully separate the zero-dynamics from the original system, and the new system is thus derived which is convenient for the output-feedback design.Then,a simple design procedure is given for the output-feedback control of the transformed sys- tem.Besides,the globally asymptotical stability of the closed- loop system can he guaranteed by the positive definiteness of the derived matrix.Finally,a simulation example is given to illustrate the correctness of the theoretical results.
