Abstract: In order to compute the Lyapunov exponent of Duffing system,this paper adopts a kind of classical method based on QR decomposition to calculate the Lyapunov exponent of Duffing system.According to the basic characteristics of the Lyapunov exponent,we presents a kind of Lyapunov exponent algorithm based on QR decomposition for the known Duffing system.By using software simulation,we know that the Duffing system Lyapunov exponent algorithm based on QR decomposition is correctness.

Key words: Duffing system, Lyapunov exponent, QR decomposition
