Design And Study On The Control System Of Magnetic Suspending Plane Based On DSP

Although the application of the magnetic field began 1000 years ago, especially, the research and application of the magnetic field has been blossom since the characteristic of the magnetic field was paid attention to at 19 century, the phenomenon of the magnetic field is very complex, we have to go ahead for study on it further.Along the development of the apparatus which require being more and more minitype, the room of the apparatus will be compact. So the magnetic suspended bearing has to be predigested. For example, the artificial heart of the magnetic suspension must be minisize to alleviate suffering of the patient; the hard disk of the magnetic suspension must be minisize to meet to the development of the computer; and so on. The conversation magnetic suspended bearing is not to meet to the requirement of the miniaturization, and the same time, the assistant bearing has to be applied if the conversation magnetic suspended bearing is applied for the magnetic suspended disk rotor. Another reason, we also hope the conversation magnetic suspended bearing be better and better for the structure and control. Taking magnetic suspending plane as research object the, design of the digital control system base on magnetic diskette of DSP and the research on algorithm are studied in this paper. The advanced control hardware plan is made, and the traditional PID algorithm and the multimode intelligent control algorithm based on pattern recognition are discussed.This paper proposes the hardware design plan of digital control system of the magnetic diskette system based on the control mathematic model, according to which the controller hardware circuit is designed with a core processor, TMS320C6713.The paper also give the optimize design at the same time, including the design of anti-abasing filter for the input signal to improve the accuracy of the signal to improve the precision of the whole system and the design of A/D conversion circuit to acquisition sensor signal without phase difference. The traditional PID algorithm is employed in control system based on the distributed control idea, and the multimode intelligent based on pattern recognition control algorithm has been discussed on the requirements of the fact to perform the good control of the system.The figures of the magnetic suspending plane according to the simulation are presented to illustrate the control system performance and the results show that this system has the advantages of high stability, high control precision, strong stiffness, fast response and.
