This book was released on 2017-10-13 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the different spatial control techniques for regulation of spatial power distribution in advanced heavy water reactors (AHWR). It begins with a review of the literature pertinent to the modeling and control of large reactors. It also offers a nodal-core model based on finite difference approximation since the AHWR core is considered to be divided into 17 relatively large nodes. Further, it introduces a nonlinear model characterizing important thermal hydraulics parameters of AHWR and integrates it into the neutronics model to obtain a coupled neutronics-thermal hydraulics model of AHWR. The book also presents a vectorized nonlinear model of AHWR and implements it in MATLAB/Simulink environment. The model of the reactor is then linearized at the rated power and put into standard state variable form. It is characterized by 90 states, 5 inputs and 18 outputs. Lastly, it discusses control techniques for a nonlinear model of AHWR. This book will prove to be a valuable resource for professional engineers and implementation specialists, researchers and students.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, we study theoretical and practical aspects of computing methods for mathematical modelling of nonlinear systems. A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation;methods for low-rank matrix approximations; hybrid methods based on a combination of iterative procedures and best operator approximation; andmethods for information compression and filtering under condition that a filter model should satisfy restrictions associated with causality and different types of memory.As a result, the book represents a blend of new methods in general computational analysis,and specific, but also generic, techniques for study of systems theory ant its particularbranches, such as optimal filtering and information compression.- Best operator approximation,- Non-Lagrange interpolation,- Generic Karhunen-Loeve transform- Generalised low-rank matrix approximation- Optimal data compression- Optimal nonlinear filtering

Available in PDF, EPUB and Kindle. Book excerpt: The High Temperature Lattice Test Reactor (HTLTR) at Richland, Washington, operates at temperatures up to 1000°C. Its low nuclear power requires a 384 kilowatt electrical heating system, that is divided into four circuits, to attain the high temperatures in the ten-foot cube of moderating graphite. This thesis describes the design and evaluation of an algorithm for digital computer control of the heating system. Design specifications for the algorithm were: (1) limited computer memory was available; (2) the ranges for the manipulated variables were limited and were different; (3) the temperature differences throughout the reactor were to be small; (4) the response was to be non-oscillatory; (5) there should be a small steady-state error; and (6) it was necessary to compensate for nonlinearities, The distributed nature of the heating system, its multitude of inputs and outputs, and its non-linearity over the operating range formed a process that was extremely difficult to describe without directly measuring the transfer function. Since the completion of the control program had to coincide with the completion of the reactor, the design of the algorithm could not wait until direct measurements on the system were made. A preliminary analysis of the reactor heating system showed that the design specifications could be met by using a discrete approximation to a continuous proportional-plus-integral controller as the framework around which to design the algorithm. The extensive logic and calculation power of the digital control computer provided the means to extend the basic form of the algorithm to meet the design specifications. A hybrid computer simulation of the heating system was designed for verifying the algorithm and for refining it to compensate for the interactions between circuits of the heating system. Important features of the simulation were: a program to optimize the control parameters by a "hill-climbing" method; and an operating program that allowed extensive changes in the digital portion of the simulation program while it was running. After the reactor was constructed, transfer functions for the heating system were obtained by step function tests to complete the hybrid simulation. In addition to amplitude scaling, time scaling by a factor of 3000 was necessary to obtain reasonable problem solution times for the control system. Extensive tests with the simulation showed that the first five design specifications were met, and that the system was stable. Extensive testing with the real system, which may take months to complete, is required to verify that the sixth specification will be met. However operating experience has shown that the feature of the algorithm to meet this specification will be necessary. General conclusions, that became obvious during the research on this thesis problem, were: simulation should be considered as a primary tool for the practical solution of complex design problems; and more development effort will be required to make advanced control concepts applicable to practical problems.
