Abstract
The invention provides a method and system for controlling ventilation cooling type permafrost subgrade based on energy dynamic balance, wherein the method comprises the steps of constructing a heat absorption predicting model; and inputting an operating condition combination of a permafrost subgrade into the heat absorption predicting model to produce a predicted heat absorption for the permafrost subgrade, and controlling a cooling system to operate based on the predicted heat absorption. The heat absorption predicting model is constructed based on a seed point algorithm of formula matrix, which comprises the steps of producing a known fitting formula; establishing a formula matrix; and calculating a predictive fitting formula corresponding to a new seed point by known seed points in the formula matrix and an index formula, and then calculating the predicted heat absorption based on the predictive fitting formula.
