Periodic Adaptive Identification and Control for a class of Discrete Time-varying Systems

Key Words:Discrete time-varying system; parametric uncertainty; Periodic adaptive control; asymptotic convergence

Abstract:In this paper, we present a discrete periodic adaptive control for systems with time-varying parametric uncertainties which are periodic, and the only priori is the periodicity. The new adaptive controller updates the parameters and the control signal periodically in a pointwise manner over one entire period, in the sequel achieves the asymptotic tracking convergence. A simulation example illustrates the feasibility and effectiveness of the proposed method.
