Some non-linear problems in the theory of automatic control

With constant coefficients

Exceeding (n-2), and its representation by powers of λ will be:

The relationships given above are valid if the coefficient of λ_ρ in the polynomial D(λ) is (-1)^n. If The polynomial is written in the form

τ 2

Negative; it will be called the feedback gain.

σ = ν – ( β – γ ) z_4 – γ ξ

σ = j_1 η_1 + j_2 η_2 + + j_3 η_3, dξ/dt = f ( σ )
