A variable fractional-order equivalent circuit model is proposed to accurately describe the dynamic characteristics of lithium-ion batteries (LIBs). Firstly, a fractional impedance (FIM) established, such that (FO) polynomial function LIB state charge (SOC). Then, chaotic adaptive particle swarm optimization (CAFPSO) method derived identify parameters FIM. Experiments reveal reliability novel approach through root-mean-squared error (RMSE) and mean absolute (MAE) terminals voltage, yielding values 8.99 mV 4.56 mV, respectively. This translates into accuracy improvements 22.5% 34.4% for (PSO) algorithm 57.9% 72.8% (AFPSO) algorithm,

Non-linear Fractional-Order Chaotic Systems Identification with Approximated Fractional-Order Derivative based on a Hybrid Particle Swarm Optimization-Genetic Algorithm Method
Although many mathematicians have searched on the fractional calculus since many years ago, but its application in engineering, especially in modeling and control, does not have many antecedents. Since there are much freedom in choosing the order of differentiator and integrator in fractional calculus, it is possible to model the physical systems accurately. This paper deals with time-domain id...

In this paper, a fractional-order robust adaptive intelligent controller (FRAIC) is designed for a class of chaotic fractional order systems with uncertainty, external disturbances and unknown time-varying input time delay. The time delay is considered both constant and time varying. Due to changes in the equilibrium point, adaptive control is used to update the system's momentary information a...
