Implantation of algorithms of diffuse control in DSPS

In this thesis work there are presented: a) The characteristics and main components used in an electronic system based on a Dsp guided to control applications of processes, b) The description of an algorithm of diffuse control whose objective is the regulation of neutron power in a model of the punctual kinetics of a nuclear research reactor type TRIGA, and c) The installation in language assembler and execution in real time of the control algorithm in the system based on a Dsp. With regard to the installation and execution of the algorithm, the reaches of the project have been delimited to the following: a) Readiness of the entrance values to the controller in specific registrations of the system Dsp, b) Conversion of the entrances to the numerical formats with those that one obtains the best acting in the control algorithm, c) Execution of the algorithm until the obtaining of the value of the controller's exit, and d) Placement of the result in specific registrations of the Dsp for their later reading for an external parallel interface. It is necessary to mention that the simulation of the punctual kinetics of a reactor type TRIGA in the Pc and its integration with the control system based on the one Dsp is had contemplated as continuation of this work and that one of those will constitute main activities in my project of master thesis. A brief description of the topics presented in this thesis is given next. In the chapter one it is presented a general description of the diffuse logic and some of their applications in the industry. The main characteristics of a Dsp are also presented that they make it different from a micro controller or a microprocessor of general purpose. In the chapter 2 details of the internal architecture of the Dsp TMS320CS0 of Texas Instruments that are not explained with detail in the manual of user of the same one. This chapter has as objective to understand the internal hardware of the Dsp that is used for to carry out the program in language assembler of the algorithm of diffuse control for the regulation of power of the TRIGA reactor presented in the chapter five. The chapter 3 treats the pattern of the punctual kinetics of a TRIGA Mark III reactor. Also they are defined basic concepts of the fission reactors. Due to the reaches of this thesis, the equations presented in this chapter are not used in the development of the controller since these they will cover in the master thesis where intends to simulate the dynamic behavior of the reactor in a Pc, but carrying out the power control functions in the system Dsp here developed. The chapter 4 explains the programming in C++ language of the diffuse controller for the regulation of power. This program is based on an algorithm developed with priority in ambient Mat lab. The program generated in C++ is used as pattern of reference to be able to evaluate the obtained results with the algorithm implanted in the Dsp. In the chapter 5 the numeric modifications carried out are explained to be able to manipulate the notation of floating point with operations among whole numbers. It is also described step to step the development of the program in the language assembler of the diffuse controller for the regulation of power of the TRIGA reactor. In the chapter 6 the obtained results there are shown with the control algorithm implanted in the Dsp. The program in C++ is used described in the chapter four for to be able to carry out the comparison of results generated exclusively by the stages that they conform the diffuse controller. As already was mentioned, later will be integrated this controller to a Pc which will simulate the behavior of the reactor. (Author)
