查询词典 frequency histogram

The performance of magnetic levitation is determined mainly by the characteristic of its controller and solving the problems of the high precision, high esponse frequency, output immune from the disturbance, the parameter perturbation and the uncertain factors from outside is very difficult. The traditional methods can not meet the needs of the system. So it has great significance to study the control method of magnetic levitation.
