Abstract :
In spite of the big performances of the predictive control based on the exact linearization of the generalized nonlinear systems presented in W.H. Chen (2004), this control strategy shows some drawbacks if the parameters of the system are unknown or time-varying, flowingly, we have implemented in M. Mrabet et al. (2005) a new control algorithm based on the online estimation of the parameters of the system. In this paper, we study the convergence of this new algorithm in term of tracking. The convergence proof is elaborated using Lyapunov stability theory
