Abstract :
This paper presents a new approach to solve the stable inversion problem of nonlinear nonminimum phase systems. Based on the recent results of Chen-Paden (1992), the minimum-energy property is first established for the solutions of the stable inversion problem. Then, an iterative algorithm via linearization, discretization and Moore-Penrose generalized inverse is constructed. This is followed by simulation results to illustrate that the exact output tracking without any transients has been achieved.
