In order to improve the accuracy of the guidance control system, the error needs to be predicted and compensated. Establishing an accurate mathematical model based on the predicted experimental data is a necessary step to improve the compensation effect. The method of establishing the error model based on the measured system error data or curve and using the estimation theory is expounded. In particular, the method of establishing the error model of the multi-dimensional system is provided to provide a mathematical model for error compensation. The results show that the system error model established by the estimation theory can achieve the required accuracy and is feasible in engineering
