Adaptive Control of Time-delayed Systems with Application for Control of Glucose Concentration in Type 1 Diabetic Patients

Individualized T1DM simulator for verification of adaptive controller

“…The time-delay τ is assumed to be known, [8]. Further, the signal ∆G M (t) [mmol/l] is the deviation of the subcutaneous glucose concentration from the steady-state value and ∆v(t) [pmol/kg/min] is the deviation of the steady-state insulin infusion rate.…”

High-Performance Adaptive Pressure Control in the Presence of Time Delays: Pressure Control for Use in Variable-Thrust Rocket Development

“…Aside from pressure control problems, the benefits of combining delay compensation, adaptation, and transient response improvement methods can be realized in a variety of domains where uncertainties and time delays play a dominant role. Various adaptive delay compensation approaches have already been implemented in a wide array of plants, including teleoperation systems [32], internal combustion engines [33], [34], biology [35], [36], space systems [37], and transportation [38]. In this article, a unique combination of an adaptive delay compensation method [39] and adaptive transient performance improvement method [40]- [43] is discussed.…”

Real‐time identification of nonlinear multiple‐input–multiple‐output systems with unknown input time delay using Wiener model with Neuro‐Laguerre structure

“…Consider the nonlinear system described in (6) and the Wiener model defined in (7). Convergence of the Wiener model outputs (ŷ(k)) to the system outputs (y(k)) is guaranteed if the weights of the MLP NN are updated using (11).…”

“…9 Some of the open problems that occur with the presence of the delay phenomenon have been discussed in the work of Richard. 10 The problem of modeling of a subcutaneous tissue, which involves a known input time delay, is investigated in the work of Tárník et al 11 In the work of Najafi et al, 12 using the wavelet transformation, a method for estimation of the input time delay has been proposed for linear systems with unknown input time delay. Rad et al 13 introduce a correlation approach for approximation of the input time delay.…”
