Based on the theory of phase space reconstruction,a low-dimension stranger attractor was reconstructed in high-dimension for brushless direct current motor(BLDCM)by one dimension time series.The features of reconstructed function are similar to the original function,which can be used to judge the dynamic status of system.The similarity was proved by comparing Lyapunov exponents using the improved Wolf method based on chaotic optimal scheme.The analysis results show that the present reconstructed method is effective,simple and quick,compared with the previous schemes which need to calculate the best reconstruction parameters.The conclusions can be used for chaotic forecasting and chaotic control.
