摘要

比例-积分-导数(PID)控制是控制主动磁轴承系统最常用的控制方法，特别是在支承刚性转子的情况下。在柔性转子支撑的情况下，最常见的控制方法还是PID控制与陷波滤波器相结合。其他控制方法，被称为现代控制理论，仍处于发展过程中，不能在实际工业应用中普遍发现。目前，它们主要用于研究应用。与PID控制相比，PI-D控制意味着衍生元件在反馈回路中而不是在系统的主干中。本文研究了PID控制和PI-D控制结合陷波滤波器的柔性转子/主动磁轴承系统的性能。通过观察系统对阶跃输入的响应进行时域分析，通过观察灵敏度函数的频率响应进行频域分析，分析了系统的性能。

Improvement of flexible rotor/active magnetic bearings system performance using pi-d control

Proportional–integral–derivative (PID) control is the most common control approach used to control active magnetic bearings system, especially in the case of supporting rigid rotors. In the case of flexible rotor support, the most common control is again PID control in combination with notch filters. Other control approaches, known as modern control theory, are still in development process and cannot be commonly found in real life industrial application. Right now, they are mostly used in research applications. In comparison to PID control, PI-D control implies that derivate element is in feedback loop instead in main branch of the system. In this paper, performances of flexible rotor/active magnetic bearing system were investigated in the case of PID and PI-D control, both in combination with notch filters. The performances of the system were analysed using an analysis in time domain by observing system response to step input and in frequency domain by observing a frequency response of sensitivity function.

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
