... branch of engineering and applied mathematics literature. Since its introduction in 1980’s, it has grown to become a major scientific domain. For example, it gained a foothold in Economics in the late ... system contains uncertainties and time-varying delay. By using theorem 3 with the choice of λ = 5, τ(t)=0.25 + 0.15 sin(t)(τ = 0.4, β = 0.15), we can obtain the following state-feedback...
