摘要

本文研究了一种开放式磁悬浮控制实验平台，采用DSP核心处理器输出信号控制线圈的励磁电流，实现浮子的稳定悬浮。采用电流位置双闭环控制方法，使得平台具备一定的抗干扰能力。为匹配课程教学，配备LCD显示屏可实时显示悬浮关键信息，实现实验的可观测性；同时开放控制算法接口，可实现控制算法的变换与参数的修改。实验结果表明，系统可实现浮子在z方向4mm左右间隙内稳定悬浮，验证了控制策略的有效性与平台的可靠性。该平台为《新能源发电与控制技术》课程教学提供了实验载体，有助于提升学生的实践能力。

Abstract

This paper studies an open magnetic levitation control experimental platform, which uses a DSP as the core processor to output signals for controlling the excitation current of the coils, thereby achieving stable levitation of the floater. A dual closed-loop control method of current and position is adopted, endowing the platform with a certain anti-interference capability. To match curriculum teaching, an LCD display is equipped to real-time show key levitation information, realizing the observability of the experiment. Meanwhile, the control algorithm interface is open, allowing the modification of control algorithms and parameters. Experimental results indicate that the system can achieve stable levitation of the floater within a gap of approximately 4mm in the z-direction, verifying the effectiveness of the control strategy and the reliability of the platform. This platform provides an experimental carrier for the course "New Energy Power Generation and Control Technology" and helps improve students' practical abilities.
