The correlation analysis and identification algorithm is used widely in engineering. The basic principle of the algorithm is discussed first. Then the Fibonacci sequence is introduced into the algorithm,and the variable step method based on the modified Fibonacci sequence is used to optimize the model parameters. The result Of simulation indicates that the rate of convergence in optimizing is improved.
