Abstract :
This paper presents an approximate dynamic inversion methodology for a class of multivariable nonaffine-in-control systems via time-scale separation. The control signal is defined as a solution of "fast" dynamics, and the coupled system is shown to comply with the assumptions of Tikhonov\´s theorem from singular perturbations theory. Simulations illustrate the theoretical results
