Abstract

The present invention proposes a passivity analysis method, in which the influence of random mixed time delay, random interference and parameter uncertainty on the passivity analysis is considered, and the Lyapunov function is constructed to fully utilize the effective information of the time delay, Compared with the passivity analysis method of the existing neural network dynamic system, the analysis method of the present invention can consider the mixed time delay, random disturbance and parameter uncertainty occurring randomly together, and obtain the solution dependent on the linear matrix inequality The passivity analysis method achieves the purpose of resisting nonlinear disturbances, and the invention is suitable for passivity analysis of nonlinear complex dynamic systems.

Description

technical field [0001] The invention belongs to the field of control, and relates to a passivity / robust passivity analysis method of a random neural network system with randomly occurring mixed time delays. The invention is applicable to the passivity analysis of nonlinear complex dynamic systems. Background technique [0002] As an interdisciplinary subject, artificial neural network has been applied in many fields, and it has important theoretical significance to study its development process and frontier issues. Because the neural network has the advantages of distributed storage of information, parallel processing and self-learning ability, it has broad application prospects in the fields of information processing, pattern recognition and intelligent control. If a neural network system wants to play a role in engineering, it must have stability. Therefore, stability analysis is an extremely important and indispensable link in the study of the core issues of neural networ...
