The invention discloses a recent historical working condition selection method based on correlation coefficients, and the method comprises the steps: firstly determining a research object which comprises an output variable under a current working condition and n input variables affecting the output variable; normalizing all the output variable data and the input variable data; calculating a correlation coefficient between the input variable and the output variable; calculating a weighted Euclidean distance between the current working condition and the historical working condition through the correlation coefficient; and finally, calculating the historical working condition corresponding to the minimum weighted Euclidean distance to be the closest working condition. According to the recenthistorical working condition selection method, the influence of each input variable on an output variable is used as a weight to ensure that the historical working condition closest to the current working condition is selecte
