Disturbance rejection using self-tuning ARMARKOV adaptive control with simultaneous identification

In this paper we present a numerical and experimental investigation of the properties of the ARMARKOV adaptive control (AAC) algorithm with simultaneo us identification. This algorithm requires a model of only the secondary pa th (control input to performance variable) transfer function which is ident ified online using the time-domain ARMARKOV/Toeplitz identification techniq ue. For a 5-mode acoustic duct model, we present numerical as well as exper imental results for single-tone, dual-tone, and broadband disturbance rejec tion. In the simulations and experiments we assume no knowledge of the dist urbance signal.
