| S Aiming at the problems of highly complex nonlinearness and slow time-varying characteristics of parameters of the first-order RC equivalent circuit model of lithium-ion battery, low accuracy of online parameter identification and poor real-time performance, this paper uses memristor, inductor, capacitor and other electronic components as loads to construct a chaotic system with the first-order RC equivalent circuit model.S Then, the adaptive synchronization control method is used to construct the controller for realizing the synchronous control of the chaotic system, and the adaptive control law of the chaotic system parameters identification is constructed to realize the real-time online identification of and parameters in the first-order RC equivalent circuit chaotic system. From the experiment and simulation results,S the parameter identification method of the first-order RC equivalent circuit chaotic system presented in this paper has the fast convergence and high accuracy. |
