In this paper, we develop a method to design the input control track output of nonminimum-phase nonlinear systems asymptotically. The is based on an exact linearization. To perform linearization, other should be selected such that its relative degree equal dimension system. Furthermore, desired which has been will set original determined by Particle Swarm Optimization. applying obtained via output-input linearization sometimes led singularity. overcome singularity problem, polynomial...
