Abstract


Maglev technology is an emerging mechatronics technology, the advantage is obvious : no mechanical friction , no lubrication , low power consumption , low noise , can greatly extend the life of the machine body . Using magnetic levitation technology ferromagnetic platform suspended in a magnetic field , non-contact linear motor drive , combined with control technology to achieve fast precision positioning has been more attention . Parameters of the perturbation in the magnetic levitation system performance merits depends largely on the characteristics of the sensor and the control method , high-precision , high response frequency and output sensors and magnetic levitation system from outside interference and outside interference of uncertainty factors are difficult to solve the thorny problem of traditional sensing device and control method is difficult to meet the system requirements , and therefore to expand the research and design of the sensor and the control method has a very important practical significance . In this paper, the suspension system of sensor and control system there . Photoelectric displacement sensing device , the establishment of a single-degree-of-freedom magnetic levitation system test bed . Then the laboratory bench to create a model of the current and voltage . Expand the basis of theoretical analysis of the system model , design a digital PID controller and H_ ∞ controller . Through computer simulation comparing the above two control methods, the effect , and the analysis of its suspension properties . The results show that : compared with classical PID control , good stability and robust H_ ∞ controller - based single-degree-of-freedom magnetic levitation system to reach equilibrium , and in a short period of time , made ??to order the suppression of interfering signals satisfactory results . DSP chip as a controller, to design the corresponding digital controller used in the experiment , the effect of the control method further verified by experiment above . The results fully affirmed H_ ∞ controller design based on H_ ∞ control method superiority : can achieve system stability suspended robustness and interference suppression capability .
