Study on fuzzy controller for lorenz chaotic system based on linear matrix inequalities method

摘要

This paper studied the stability of Lorenz chaotic system control problem. Adopted fuzzy dynamic model approaching non-linear chaotic system to make non-linear chaotic system into a fuzzy local linear model. Used linear matrix inequalities (LMI) theory to solve the fuzzy controller parameters and the public's positive definite matrix P, set up the conditions for the stability control system. Simulation to verify the effectiveness of the program.
