The paper presents a solution for the 18O isotope separation process control. The separation process is a non-linear one and it is modeled using the fractional-order systems theory, in order to obtain a higher accuracy. Based on the considered model, an Internal Model Control strategy is proposed for the 18O isotope concentration control. The used controller is an adaptive fractional-order one and...
Auxiliary noise, injected in active noise control (ANC) system for on-line secondary path modeling (SPM), contributes to the residual error (which we want to minimize). In this paper, two new schemes for controlling the auxiliary noise injection are proposed. The first method is ON/OFF control in which an additional fixed filter is used to temporarily hold the tap-weights of the adaptive on-line SPM...
