【摘要】：电磁悬浮轴承是利用磁力实现无接触的新型轴承,具有无接触、不需要润滑和密封、振动小、使用寿命长、维护费用低等一系列优点,属于高技术领域,具有一系列传统轴承无可比拟的优点,拥有广阔的应用前景。磁浮轴承的研制不仅可以填补国内空白,而且可以带动机电行业的很多相关企业进行产品结构调整,形成新的经济增长点。电磁轴承的研究最重要的是建立数学模型和设计控制系统,并设计仿真软件。本文针对单自由度电磁轴承系统做了如下工作: (1)电磁轴承控制系统数学模型的建立。在连续时间系统下,这里针对单自由度电磁轴承的结构,利用磁力轴承电磁力的线性化,进行化简,进行拉普拉斯变换,从而推导出单自由度电磁轴承控制系统数学模型。 (2)电磁轴承自动控制模块控制系统的研究,主要进行传统PID控制的仿真研究,然后对其使用智能控制方法进行改进。 (3)使用Delphi软件设计电磁轴承可视化仿真软件,对传统PID控制器以及CMAC控制器、非线性控制器进行仿真。
[Abstract]:Electromagnetic suspension bearing is a new type of non-contact bearing using magnetic force. It has a series of advantages, such as no contact, no lubrication and seal, small vibration, long service life and low maintenance cost, etc. It belongs to the field of high technology. With a series of unparalleled advantages of traditional bearings, has a broad application prospects. The development of maglev bearings can not only fill the gap in China, but also drive many related enterprises in the electromechanical industry to adjust the product structure and form a new economic growth point. The most important research of electromagnetic bearing is to establish mathematical model and design control system, and design simulation software. The main work of this paper is as follows: (1) the mathematical model of electromagnetic bearing control system is established. In the continuous-time system, according to the structure of single-degree-of-freedom electromagnetic bearing, this paper uses the linearization of magnetic force of magnetic bearing to simplify and carry on Laplacian transformation, thus deduces the mathematical model of the control system of single-degree-of-freedom electromagnetic bearing. (2) the research on the control system of the automatic control module of the magnetic bearing, mainly carries on the simulation research of the traditional PID control, then carries on the improvement to its using the intelligent control method. (3) the visual simulation software of electromagnetic bearing is designed by using Delphi software, and the traditional PID controller, CMAC controller and nonlinear controller are simulated.
