“…In literature, the 2-point reactor kinetics was applied numerous times (Ansarifar and Saadatzi, 2015;Eliasi et al, 2011;Hui and Yuan, 2022a;Li, 2014a;b;Li et al, 2014b;Na et al, 1998b;a;Na, 2001;Parhizkari et al, 2015;Saadatzi and Ansarifar, 2017;Yadav et al, 2018), optionally using the prompt jump approximation (Onega and Kisner, 1978;Kobayashi and Yoshikuni, 1982;Winokur and Tepper, 1984;Marseguerra et al, 2003) or even the quasi-static approximation (Shimazu, 1995), and most frequently taking into account a single or three delayed neutron precursor groups. 2-point kinetics model may be coupled with a thermal hydraulic calculation (Pradhan et al, 2016) for a more precise description of the changes in the coolant/moderator temperature and density.…”

“…In the past, load following capabilities of nuclear reactors have been studied in numerous references, which are reviewed in the main part of this paper. They mostly rely on single point kinetics (Aboanber et al, 2014;Arab-Alibeik and Setayeshi, 2005;Ben-Abdennour et al, 1992;Edwards et al, 1990;Elsisi and Abdelfattah, 2020;Hui et al, 2020;Hui and Yuan, 2021;2022c;d;Khajavi et al, 2002;Khorramabadi et al, 2008;Li and Zhao, 2013a;b, 2014;Liu and Wang, 2014;Mousakazemi, 2019;Nair and Gopal, 1987;Park and Cho, 1992;Torabi et al, 2011;Wang et al, 2019;Zarei et al, 2016) or multi-point kinetics (Ansarifar and Saadatzi, 2015;Eliasi et al, 2011;Hui and Yuan, 2022a;b;Kobayashi and Yoshikuni, 1982;Li, 2014a;b;Li et al, 2014b;Marseguerra et al, 2003;Na et al, 1998b;a;Na, 2001;Onega and Kisner, 1978;Parhizkari et al, 2015;Pradhan et al, 2016;Saadatzi and Ansarifar, 2017;Shimazu, 1995;Winokur and Tepper, 1984;Yadav et al, 2018) or on 1D time-dependent diffusion codes (Christie and Poncelet, 1973;…”

An overview of power reactor kinetics and control in load-following operation modes

et al. 2023

Previous work done on reactor kinetics and control in load-following operation modes available in open literature is reviewed. The analysis is focused on, however not limited to pressurized water reactors. Different approximations of the time-dependent neutron transport problem as well as different control algorithms are described in detail and compared. Due to lack of published information the majority of the comparisons was done on qualitative level. In order to facilitate future testing and intercomparisons of models and algorithms, two so-called reference scenarios with time-dependent power demand are defined: a scenario to test the limitations of the load-following capabilities of the nuclear facilities and a second, quasi-realistic scenario.

“…Recently, several studies have used the active disturbance rejection control (ADRC) technique in nuclear reactor control loops owing to its effectiveness in dealing with system nonlinearities and modelling uncertainty as well as parametric variations. Besides, it is simple to implement and tune, and requires minimal plant information in terms of the relative degree and input gain [16]- [19]. However, most of the studies on ADRC do not consider the effect of measurement noise which is ubiquitous in practical systems and degrades the quality of estimates obtained via extended state observers (ESO) which in turn limits the achievable closed-loop performance.…”

This paper introduces a robust position tracking control structure of exoskeleton robots (ERs). An open environment and body flexibility are the main challenges in ER control system design. First, a fractional‐order nonsingular terminal sliding mode (FONTSM) controller is proposed for a robotic manipulator with uncertainty, where lumped unknown dynamics are computed by time‐delay estimation (TDE). Secondly, a robust exact differentiator (RED) is employed as the output feedback observer for the velocity sensorless robotic system. Thirdly, the stability of the FONTSM control system is demonstrated. It is proved that the system error can move to the specified value along the sliding mode surface at a fixed time and can reach the sliding mode surface after a finite time. Finally, simulations on a 2‐DOF robotic manipulator show the effectiveness of the fixed‐time control strategies. When a combined trigonometric function disturbance is applied, the joint angle error is reduced to 1% by the model‐free controller based on output feedback within approximately 1 s.
