Abstract

In this article, a fuzzy adaptive fractional-order proportional plus derivative controller for total power control of an Advanced Heavy Water Reactor is designed in the presence of thermal hydraulics feedback. In addition to a conventional Fuzzy Logic Control layer (FLC), the proposed controller uses a self-tuning FLC layer for run-time adaption of the controller output. A genetic algorithm (GA) based optimization method is used for tuning the controller parameters. Transient Simulation studies are carried out to demonstrate the efficacy of the proposed controller for set-point changes and feedwater temperature disturbances. Results of the proposed controller are compared with those of the traditional proportional plus derivative (PD) and fractional-order proportional plus derivative (FOPD) controllers using standard performance indices. It is observed that the AFOPD controller has 13.99% performance improvement over the FOPD controller and 20.53% improvement over the PD controller for considered objective function. At various operating conditions also, the AFOPD controller shows similar superiority over FOPD and PD controllers.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
