关 键 词：Elevator Traffic Flow Chaos Phase Space Reconstruction Largest Lyapunov Exponent
摘 要：正In this paper,nonlinear time series techniques are applied to analyze the peak elevator traffic flow *** phase space,which describes the evolution of the behaviour of a nonlinear system,is reconstructed using the delay embedding theorem suggested by *** embedding parameters,*** delay time and the embedding dimension are estimated using the mutual information of the data and the false nearest neighbor algorithm,*** the attractor of the elevator traffic flow from reconstruction is not necessarily sufficient indication of chaos,therefore we then calculate the correlation dimension of the resulting attractor and the largest Lyapunov *** is demonstrated that the traffic flows of the up-peak and down-peak all exhibit low-dimensional chaotic *** result will help to adjust the group control scheduling methods according to the chaotic behaviour of the peak flow so as to increase the performance index.
