| Abstract: | In order to realize the suspending control of the globe with hybrid-excited magnets,the paper adopts a new control arithmetic pseudo-derivative-feedback (PDF).Based on the arithmetic the paper studies the mathematical model of the system by ways of mechanics analysis and theoretical calculation.It deduces the transferring functions of the controlled object and the controlled system,and analyses its control capability. The study results show that the PDF control solution possess the characteristics of robustness and high control precision,comparing the nonlinear instability of the hybrid-excited magnet system. |
