【摘要】：由于磁路在磁軸承定子磁極間的耦合,磁力的分布會發(fā)生變化,致使理論模型推導(dǎo)的控制電流難以提供準(zhǔn)確的回復(fù)力。基于Boit-Savart定理建立了磁場分布模型并分析了磁路耦合的影響因素;建立了考慮磁路耦合的磁力等效模型;分析了磁路耦合對磁力誤差的影響,并提出了解耦控制策略;進(jìn)行了電磁場仿真,驗(yàn)證了解耦控制的正確性;通過磁軸承穩(wěn)態(tài)懸浮實(shí)驗(yàn),驗(yàn)證了解耦控制策略的有效性。
[Abstract]:Due to the coupling of the magnetic circuit between the magnetic poles of the stator of the magnetic bearing, the distribution of the magnetic force will change, which makes it difficult for the control current derived from the theoretical model to provide an accurate return force. Based on the Boit-Savart theorem, the magnetic field distribution model is established and the influencing factors of magnetic circuit coupling are analyzed, the equivalent magnetic force model considering magnetic circuit coupling is established, the influence of magnetic circuit coupling on magnetic force error is analyzed, and the decoupling control strategy is proposed. The simulation of electromagnetic field verifies the correctness of decoupling control, and the validity of decoupling control strategy is verified by the steady suspension experiment of magnetic bearing.
