Bounded Stability in Networked Systems with Parameter Mismatch and Adaptive Decentralized Estimation

Saeed Manaffam, Alireza Seyedi, Azadeh Vosoughi et al.

Here, we study the ultimately bounded stability of network of mismatched systems using Lyapunov direct method. The upper bound on the error of oscillators from the center of the neighborhood is derived. Then the performance of an adaptive compensation via decentralized control is analyzed. Finally, the analytical results for a network of globally connected Lorenz oscillators are verified.

Synchronization in Networked Systems with Parameter Mismatch: Adaptive Decentralized and Distributed Controls

Saeed Manaffam, Alireza Seyedi, Azadeh Vosoughi et al.

Here, we study the ultimately bounded stability of network of mismatched systems using Lyapunov direct method. We derive an upper bound on the norm of the error of network states from its average states, which it achieves in finite time. Then, we devise a decentralized compensator to asymptotically pin the network of mismatched systems to a desired trajectory. Next, we design distributed estimators to compensate for the mismatched parameters performances of adaptive decentralized and distributed compensations are analyzed. Our analytical results are verified by several simulations in a network of globally connected Lorenz oscillators.
