“…Neglecting the mutual inductance coupling caused by the rotor eccentricity, the controllable magnetic suspension force components along the α ‐ and β ‐coordinate axes can be expressed as follows : centerFα=Knormalmis2dψ1d+is2qψ1qFβ=Knormalmis2dψ1qis2qψ1d where ψ 1 d and ψ 1 q are the air gap flux‐linkage components along the d‐ and q‐ coordinate axes; i s2 d and i s2 q are the suspension control current components along the d‐ and q‐ coordinate axes; and K m is the stiffness coefficient of controllable suspension force, which can be expressed as follows : Knormalm=πLm24μ0italiclrW1W2 …”

“…The inverse system method is a feedback linearization decoupling method applied to a complex nonlinear system . There has been some research progress on the inverse system decoupling of the BLIM system . But in these studies, in order to simplify the state equation, the current dynamics of the stator winding is ignored, and therefore the dynamic decoupling performance is limited to a certain extent.…”

“…Bearingless technology is applicable for all kinds of AC motors [12,17,20,21,27]. Because of the robust and compact structure, the bearingless induction motor has become a hot research topic [18,20], [26][27][28][29][30][31][32], but there exists a complicated electromagnetic coupling in the bearingless induction motor [30,31]. To achieve its high performance control, it is necessary to realize the dynamic decoupling between different variables.…”

“…But the inverse system model is hard to accurately obtain in engineering practice. [13][14][15] Using the nonlinear approximation ability of neural network, neural network inverse system method can identify BIM inverse model and solve the tough problem of obtaining the accurate inverse system model, but the neural network's own defects (local minimum, complex computation, over learning, structure type choice over relying on experience, etc.) limit the further application of the neural network inverse system method.…”
