To provide a terminal pressure controller capable of easily generating a process model, and executing driving training for supporting even an inexperienced operator to control a terminal pressure.

This device is provided with a data collecting means 10 for collecting the measured signal of a pressure gauge set in a water service pipe network, a result data DB 101 for storing the collected signals, a data standardizing means 11 for standardizing the data, a correlation analyzing means 121 for analyzing the correlation relation of the standardized data, a data selecting means for selecting data to be used for model generation from the analytic result, a variable selecting means 123 for automatically selecting data proper as the input of a model from the selected data, a model constructing means 124 for generating a terminal pressure estimated model by multiple regression analysis by using the data automatically selected by the data selecting means, a model testing means 125 for testing whether or not the terminal pressure estimated model is proper, and a model display means 13 for carrying the result based on each means.
