The invention relates to an optimization method of a hot strip rolling production process control system, which belongs to the technical field of hot strip rolling control. The method comprises the following steps of: data collection, de-noising processing, coefficient optimization, verification test, on-line application and the like. According to the coefficient optimization step, through correlation analysis of influence between model coefficients and parameters, the model coefficients are fit, an algorithm error precision is selected, and when a calculation error is less than the algorithm error precision, the coefficient optimization step is stopped to obtain new model coefficients and corresponding offsets. According to the optimization method, through sampling and carrying out fitting analysis on a large number of steel rolling historical data, and optimizing hot continuous rolling force model coefficients, the optimization of the hot strip rolling production process control system is realized, the hot strip rolling production process control accuracy is effectively improved, and considerable economic value and practical value are achieved.
