In nonlinear control, Aizerman's conjecture or Aizerman problem states that a linear system in feedback with a sector nonlinearity would be stable if the linear system is stable for any linear gain of the sector. This conjecture was proven false but led to the (valid) sufficient criteria on absolute stability.

  • 阿依熱爾曼猜想(Aizerman's conjecture)或阿依熱爾曼問題猜想(Aizerman problem)是非線性控制的猜想,認為一線性系統有非線性的回授,不過是在一個扇形的線性區間內,若線性系統在此扇形線性區間都穩定,則整個系統都會穩定。 阿依熱爾曼猜想在一維系統成立,在二維系統是全域穩定的充份必要條件,而針對維度大於3的情形,這個猜想已找到反證,不過後來因此推導出(有效的)非線性控制全域穩定性準則。 (zh)
