Chaotic character Analysis of Ship Power Load Time Series

摘要

chaos character of ship power load was analyzed through the quality and ration angle, power spectrum approach to quality angle was presented, correlation dimension and the most Lyapunov exponent were computed by the reconstruction of phase-space. Results showed that the chaotic character of ship power load may exist, and chaotic character of ship power load not only can offer time series prediction model, but also can provide further support for application of fractal theory in singularity of ship power load.
