Identification methodology steps
Ikhouane et. al. Previous considerations
Step 1 Excite the system with a T-periodic input signal convex in its loading part
Step 2 Compute k x
Proof
¯F(T + ) + ¯F(0)
k x =
ẋ(0) + ẋ(T + )
Step 3 Compute θ(x)
Proof
θ(τ) with τ ∈ [0, T + ] is now known, then
k w¯w(τ) = ¯F(τ) − k xẋ(τ) θ(τ)
k w¯w(x) = θ(x)
