The goal of this paper is to extend the adaptive control problem of parametric strict feedback form nonlinear
systems, using Immersion and Invariance to the case of unknown, possibly, time-varying control direction. The idea is to
immerse a target system in Rn1, which is stabilized through the design of virtual controllers into an extended system in
Rn+p. The designed controller takes advantage of the wellknown Nussbaum functions to deal with the unknown sign of
input multiplier and is designed through the manifold dynamic belonged to Rp+1. The effectiveness of the proposed method is shown through simulation and is also compared to the classical adaptive backstepping approach with unknown control direction.
