英文摘要： Bearingless switched reluctance motors can realize electromotion/generation in high speed and superspeed without lubrication, so they have wide prospects. However,there exists nonlinear strong coupling between suspension force and rotary force, which is very hard to decoupling and has formed the main bottleneck that restricts the popularization and application of this technique. A novel double-stator bearingless switched reluctance motor is proposed in this project, then its electromotion/generation mechanisms and control methods will be studied. Main works are as follows: Firstly, magnetic field and coupling characteristics will be analyzed. Secondly,key parameters will be designed based on the LS-SVM and PSO algorithms. Thirdly,the mathematical models of suspendsion force, rotation force, voltage and power output will be set up under electromotion/ generation state. Fourthly, with SVMI nonlinear decoupling methods, the running strategy anf control algorithms for speed regulation under electromotion state and voltage and power output inferential control for generation state will be studied, and then detection and control algorithms will be calculated, disintegrated, and modularized. Finally, high speed parallel signal system and corresponding conreol software will be contrusted. This project combines theory and
