A fractional-order generalized SIRS model considering incubation period is established in this paper for the transmission of emerging pathogens. The corresponding Hopf bifurcation is discussed by selecting time delay as the bifurcation parameter. In

Fractional differential equations, which are non-local and can better describe memory and genetic properties, are widely used to describe various physical, chemical, and biological phenomena. Therefore, the multi-agent systems based on discrete-time

Abstract This paper focuses on the mean‐square output consensus of heterogeneous multi‐agent systems, in which the communication noises are taken into consideration. Through internal model principle and control gain function, the novel state feed

Parameter estimation is an important issue in nonlinear science, which can be formulated as a multi-dimensional problem. Numbers of nature-inspired meta-heuristic algorithms have been applied for parameter estimation of chaotic systems; however, many
