Description
絶対値(i[kT]) < Δ/2 の場合 ⇒ o[kT] = 0
i[kT] ≧ Δ/2 の場合 ⇒ o[kT] = i[kT]-Δ/2
i[kT] ≦ -Δ/2 の場合 ⇒ o[kT] = i[kT]+Δ/2
ここで、Δは、能動型磁気ベアリングの空隙の割合(好ましくは、30から50%の範囲内)に対応する定められた閾値である。
絶対値(i[kT]) < Δ/2 の場合 ⇒ o[kT] = 0
i[kT] ≧ Δ/2 の場合 ⇒ o[kT] = i[kT]-Δ/2
i[kT] ≦ - Δ/2 の場合 ⇒ o[kT] = i[kT]+Δ/2
ここでΔは、空隙の割合(一般的には、ローターの最大位置の30から50%の範囲内)に対応する定められた閾値である。
U(p)/Y(p) = (K/(1+K))×(1+aT1p)/(1+T1p)
ここで、A = 1+K、およびT1 = (1/(1+K))×Tである。
