Abstract

This article addresses the problem of stability and gain analysis for fractional-order cone-invariant systems subjected to time-varying distributed delays. Depending on the Banach fixed point theorem, the system’s solution is demonstrated to exist uniquely. Subsequently, a necessary and sufficient criterion is deduced to guarantee the cone invariance of delayed systems using a fractional differential operator. By combining the partial order relation on proper cones with the inductive reasoning, the asymptotic stability of fractional-order cone-preserving systems with distributed delays is demonstrated, with stability conditions that are equivalent to those of systems with constant delays. Furthermore, an explicit representation of cone-induced gain is put forward for cone-invariant systems in the presence of delays via utilizing the comparison principle, revealing that the cone-induced gain depends on the duration of the distributed delays. Finally, numerical simulations are performed to verify the rationality of the obtained results.
