This paper investigates the pth moment asymptotic stability of trivial solutions to uncertain dynamical systems with time-delays. The generalized expected value based on uncertainty theory is introduced and its properties are discussed. Sufficient conditions for ensuring the stability of uncertain delay systems are derived using the Lyapunov direct method. Several illustrative examples with numerical simulations are provided to demonstrate the effectiveness of the stability results.
Time-delay is a universal phenomenon in control systems, which usually leads to instability and poor performance of systems. In this paper, the pth moment asymptotic stability of trivial solutions to uncertain dynamical systems with time-delays is investigated. The concept of the generalized expected value is introduced with its properties based on uncertainty theory. Sufficient conditions for ensuring the stability of uncertain delay systems are derived by Lyapunov direct method. Several illustrative examples with numerical simulations are arranged to demonstrate the effectiveness of the stability results.(c) 2023 International Association for Mathematics and Computers in Simulation (IMACS).
