Object-oriented Software Engineering Research And Active Magnetic Bearing Control System Implementation

The Object-Oriented analysis and design methodology emerged in the 1980s. Now, it has been used to develop thousands of information systems. Object-Oriented programming is becoming the dominant programming strategy for software design.Active Magnetic Bearing (AMB) is one of outstanding technology, and the research come down to electromagnetic, control theory, machine, rotor dynamics and computer science, and so on. On the other hand, with the technology of AMB is known and mastered gradually, AMB will be applied to these fields far and wide: aviation and spaceflight, vacuum technology, machine tool and tail-wagging engineer, energy source and traffic, and so on.Firstly, this thesis introduced Object-Oriented design ideas. Then the thesis narrated Object-Oriented software engineering (OOSE) and its apply in analysis and design for real time system. Based on the analysis of AMB working principium, AMB real time controlling system was designed with OOSE. At last, we give the hardware design, debugging and DSP realization to the digital controller, make the four-axis rotate axis suspend steadily and high-speed rotation (above to 60000 min"1,radial flounce limited in 20 p. m ) in AMB which based in TMS320F240.
