Abstract
Tracking load changes in a pressurized water reactor (PWR) with the help of an efficient core power control scheme in a nuclear power station is very important. The reason is that it is challenging to maintain a stable core power according to the reference value within an acceptable tolerance for the safety of PWR. To overcome the uncertainties, a non-integer-based fractional order control method is demonstrated to control the core power of PWR. The available dynamic model of the reactor core is used in this analysis. Core power is controlled using a modified state feedback approach with a non-integer integral scheme through two different approximations, CRONE (Commande Robuste d'Ordre Non Entier, meaning Non-integer order Robust Control) and FOMCON (non-integer order modeling and control). Simulation results are produced using MATLAB® program. Both non-integer results are compared with an integer order PI (Proportional Integral) algorithm to justify the effectiveness of the proposed scheme.

6 Simulation Results Due to the sensitivity of the nuclear reactor, it is difficult to follow the core power according to load changes
Summary
Nuclear power generation is a cost-competitive source of clean energy It provides a stable baseload of energy. Nuclear power plants equipped with pressurized water reactors (PWRs) are very concerned with controlling their power output while changing their loads. There are scopes for better control schemes to be demonstrated for the purpose of core power control in a pressurized water reactor while following the required load changes. An approach to control core power in pressurized water reactors based on non-integer order control is presented in this paper. This paper continues as follows: In Section 2, we discuss basic concepts of dynamic models for pressurized water reactors. Comparisons of integer and non-integer order control schemes are provided . It is assumed that the nominal core power remains constant, q is represented as relative core power
