Relative performance Γ for all sets of parameters$\underset{˜}{\theta }$= { σ , ω , τ } evaluated. The viscoelastic constant τ has a negligible effect beyond ~10 $\overline{t_r}$. Furthermore, with lower values of tolerance σ, the set of acceptable parameters {ω, τ} is reduced. However, the relative gain Γ may be significantly larger than that obtained with greater tolerances.
