【摘要】：電磁軸承具有無(wú)摩擦、不需潤(rùn)滑、可長(zhǎng)時(shí)間高速運(yùn)行等優(yōu)點(diǎn),廣泛應(yīng)用于高速旋轉(zhuǎn)機(jī)械、特殊工作環(huán)境旋轉(zhuǎn)機(jī)械等領(lǐng)域。電磁軸承系統(tǒng)的數(shù)學(xué)模型對(duì)于系統(tǒng)分析和控制器設(shè)計(jì)具有重要意義,但受各種因素影響,計(jì)算模型誤差較大,往往不能滿足設(shè)計(jì)調(diào)試要求。因此,現(xiàn)場(chǎng)測(cè)試是獲取系統(tǒng)模型的重要手段。提出一種電磁軸承支承的柔性轉(zhuǎn)子的測(cè)試與建模方法,該方法通過(guò)正弦掃描試驗(yàn)獲取閉環(huán)系統(tǒng)頻響模型,通過(guò)變換得到開環(huán)頻響模型,然后通過(guò)辨識(shí)得到轉(zhuǎn)子傳遞函數(shù)模型,并在實(shí)際系統(tǒng)上驗(yàn)證了提出的方法。
[Abstract]:Electromagnetic bearings have the advantages of no friction, no lubrication and can run at high speed for a long time. They are widely used in high speed rotating machinery and special working environment. The mathematical model of AMB system is of great significance for system analysis and controller design. However, due to the influence of various factors, the error of calculation model is large, which often can not meet the requirements of design and debugging. Therefore, field testing is an important means to obtain system model. A testing and modeling method for flexible rotor supported by active magnetic bearing is proposed. The frequency response model of closed loop system is obtained by sine scanning test, the open loop frequency response model is obtained by transformation, and the rotor transfer function model is obtained by identification. The proposed method is verified on the actual system.
