Fractional-Order Interval Observer for Multiagent Nonlinear Systems

A framework of distributed interval observers is introduced for fractional-order multiagent systems in the presence nonlinearity. First, a frame was designed to construct upper and lower bounds system state. By using monotone theory, positivity error dynamics could be ensured, which implies that trap original Second, sufficient condition applied guarantee boundedness observers. Then, an extension Lyapunov function fractional calculus field basis condition. An algorithm associated with procedure observer design also provided. Lastly, numerical simulation used demonstrate effectiveness observer.
