Description
Summary:In this study, a magnetic-levitation (maglev) precise-position device will be addressed. The precise-position device will be designed to avoid friction in motion by using a non-contact track made up of permanent magnets and a bipolar active electromagnetic levitation platform. First, a nonlinear electromagnetic force will be analyzed thoroughly and the dynamic model of the precise-position device will be derived. Moreover, the levitation or landing force will produced by individual electromagnet with appropriate exciting current, which is decided according the designed control effort passing through the linear servo current amplifier and the bipolar switching circuit. Finally, the effectiveness and robustness of the proposed novel adaptive control strategy in this study is verified by microcontroller-based experimental results.
