Purpose: This article will report results from the in-vivo application of a previously published model-predictive control algorithm for MR-HIFU hyperthermia. The purpose of the investigation was to test the controller’s in-vivo performance and beha

In this paper we formally describe the hybrid integrator-gain system (HIGS), which is a nonlinear integrator designed to avoid the limitations typically associated with linear integrators. The HIGS keeps the sign of its input and output equal, thereb

In this paper, an offset-free MPC scheme is developed to improve performance and robustness of temperature control in magnetic resonance-guided high-intensity focused ultrasound hyperthermia cancer treatments. The proposed design effectively handles

Data-driven tuning of a hybrid integrator-gain system

Autor: Natalia Irigoyen, MF Marcel Heertjes, D.A. Deenen

Publikováno v: IFAC-PapersOnLine. 50(1):10851-10856

In an attempt to surpass Bode's gain-phase relationship, a hybrid integrator-gain system is studied that has significantly less phase lag in its describing function description when compared to a linear integrator. The hybrid integrator is designed t

This paper discusses a novel hybrid integrator design that (a) gives improved low-frequency disturbance rejection properties under double-integrator control, but (b) avoids the unwanted occurrence of overshoot and settling effects otherwise resulting
