Abstract

The invention provides an analyzing method for passivity. In the method, influences on analysis of passivity by mixed time lag with random occurrence, random interference and parameter uncertainty areconsidered, a liapunov function is constructed, and effective information of time lag is completely utilized. Compared with an existing analyzing method for passivity of a neural network dynamic system, the mixed time lag with random occurrence, random interference and parameter uncertainty are considered together, in this way, the analyzing method for passivity depending on a linear matrix inequality solution is obtained, and the purpose of resisting non-linear disturbance is achieved. The method is suitable for analyzing the passivity of a non-linear complex dynamic system.

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...
