Assumes knowledge of the limit cycle → (x(τ), ¯F(τ)) by a variable τ ∈ [0, T]<br />
Only the loading part of the input signal is considered τ ∈ [0, T + ]<br />
The equation of the loading part is<br />
¯w(x) = ψ + σ,n (ϕ+ σ,n [−ψσ,n(ρ(Xmax − X min))] + ρ(x − X min ))<br />
Its derivative is<br />
Proof<br />
Theorem 1 shows that<br />
d¯w(x)<br />
= ρ(1 − ¯w(x))<br />
dx<br />
x = X min → τ = 0 → −ψ 1,1 (ρ(X max − X min ))<br />
x = X max → τ = T + → ψ 1,1 (ρ(X max − X min ))<br />
