Abstract: This study attempts to develop pilot modeling accuracy formulae and a method to improve the accuracy of pilot model identified from the real time simulation experiments. The developed formula in this paper is on the basis of the formulae proposed in reference. The major advantage of developed formula is that it can incorporate the combined effects of the two stages of the pilot model identifications: identification of the pilot description function from the real time simulation experiments and the parameter identification of the pilot model from the pilot description in the frequency domain. The advantage of the formula offers a basis on which the method to improve the pilot modeling accuracy is built according to sensitivity analysis for the pilot model parameter in the frequency domain. Practical application verifies the validity of the method.
