【Abstract】 As the modernization of our country is developed rapidly, the demand for the energy is more urgent and more important, in the development of the medium and small-scale waterpower resourses , have put forward higher and higher demand to the performance of the governor too. In a large number of recent scientific research and production practices, the hydraulic turbine governor makes considerable progress, update from such many aspects as the control method , processing technology ,etc. constantly. Especially permeate , gain thorough understanding through comprehensive study of the subject with other disciplines and new technologies each other, for instance hydraulic pressure technology , little electronic engineering ,etc, make the design and manufacture of the governor break through the specialized category of the water and electricity, become an item of various , multi-disciplinary integrated products of new-type electromechanical liquid.This text is devoted to the hydraulic turbine governor of computer based on DSP to study , regards hydraulic turbine governor as the research object, have proposed since exactly fixes the control strategying. Regard DSP as the core at the same time and control the chip, propose the whole design plan of the system, and function as the detailed explanation to the software and hardware of the system , done certain explanation to DSP development environment. Study the problem in establishment problems and algorithms of different key software within digital signal processor; Have the computer and communication question of making the microsystem; Have the design of the computer software and work out; The integration of different systematic module , finish the design of the controller. Sketch it as follows:Chapter one: Review the developing history of the hydraulic turbine governor and current situation in recent years, introduce new direction and new development in governor reseach; Put forward systematic structure , control strategy , control component , hydraulic pressure basic research and new-type oil gear person who develop new thinking of.Chapter two: Characteristic of the routine hydraulic turbine governor; And in term of helping the project to develop and adopt , propose the main purpose and task of this text: Develop new-type DSP hydraulic turbine governor.Chapter three: Introduce the development environment of DSP systemChapter four: Through analysing the basic hardware of DSP hydraulic turbine computer governor , have explained DSP hydraulic turbine computer governor control strategy and controlled the course.Chapter five: Introduce the mathematics models of the hydraulic turbine group and MATLAB artificial software, use it for examining every characteristic of the governor; Is it transfer speed systematic superiority while being above-mentioned to prove further.Chapter six: In order to improve the governor efficiency , have designed the perfect governor and news report of having computer.Finally, the full text of brief summary, point out the weak point and propose the striving direction in the future.更多还原
