【Abstract】 The operating principle of single degree of freedom Permanent and Electronic Hybrid Magnetic System is introduced. A method of calculating PEHMS by using alternately permanent and electronic magnetic flux is put forward, and gain theory formula of magnetic induction intensity and magnetic suspension force of PEHMS, based on the principle of the mechanics, electromagnetism, electronics and dynamics. The theory mathematical mode and experimental mode are established. With the help of computer simulating software-Matlab6.0, The control system’s structure is analyzed and the relationships of the parameters of controller and the stability of system are obtained. After stable levitation, a circumrotation controller is designed, which produces rotation magnetic field making the levitated object rotate. The control strategy and controller’s model are demonstrated and analyzed .In the control system, a good linearity, high sensitive, quick response speed PSD displacement sensor is designed, whose characteristic is well fit for the suspension system. Above all, the debug of the whole system is made , the object is levitated and circumrotates successfully.更多还原
