Tuning Generalized Predictive PI controllers for process control applications
ISA Transactions, 2022 Predictive PI (PPI) controllers have demonstrated to exceed traditional PID controllers when they are applied to systems with long delays. This work proposes a new controller structure and tuning that we call Generalized Predictive PI (GPPI) controller which provides greater design flexibility than PI and PPI strategies.

Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
, 2011 The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

AgRP neurons shape the sperm small RNA payload
Scientific ReportsPaternal dietary patterns and obesity can affect offspring through epigenetic signals in sperm RNA. By activating hypothalamic Agouti-related peptide (AgRP) neurons in mice to simulate obesity’s effects, we observed changes in the small noncoding RNA ...

Hybrid LQR-PI Control for Microgrids under Unbalanced Linear and Nonlinear Loads
Mathematics, 2020 A hybrid Linear Quadratic Regulator (LQR) and Proportional-Integral (PI) control for a MicroGrid (MG) under unbalanced linear and nonlinear loads was presented and evaluated in this paper. The designed control strategy incorporates the microgrid behavior,

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...
