碩士 === 南開科技大學 === 電機與資訊工程研究所 === 97 === Magnetic Suspension System is a repulsive and attractive one combining permanent magnet and electromagnet and the system was controlled by PID controller in the early researches. This paper was conducted with a PID controlling system as well. It found out the modes of functions by the efficiency differences of PID controllers. During conducting the research, it tended to inquire the types of magnetic power production and magnetic principium of Magnetic Suspension System, and it completed the electrical parts as well as the driving circuit which used the technics of PWM （Pulse Width Modulation） to reduce coil temperature and achieve the Magnetic Suspension System. The digital signal processing unit-DSP F2812 was used as the controller core in this paper, and it also constructed the PID controller. The fixing position speed of Magnetic Suspension System was discovered by the combination of both the hard ware and soft. In the last part of this research, it tended to find out the differences of fixing position speed and resisting step response from the measuring data.
