In the improved Duffing system,detection signal is quite weak,hence,solving the chaos threshold takes a lot of time when one applies Lyapunov exponent criterion. The paper proposes a bisection algorithm to solve the problem.The algorithm can figure out the threshold value whcih makes Duffing system transfer from chaos state to period state.First,we take 0. 1 as the step length to find a threshold roughly based on the Lyapunov exponent. Then the bisection algorithm figures out the exact value for the threshold. The speed of calculating is speeded a lot,Simulation result proves the validity of this method.
