The invention discloses a double-capacity water tank liquid level system dynamic characteristic modeling method and system and a storage medium, all related parameters are identified through a proper parameter identification method before a model is practically applied, and the requirement of online parameter identification for the hardware calculation speed of a control system is reduced. At any working point of the system, the model can be converted into a linear ARX model, so that the design of a liquid level prediction control algorithm of the double-capacity water tank is facilitated. The model has global nonlinear description capability, can be converted into ARX models with different parameters aiming at different working points of the double-capacity water tank liquid level control system, and is a nonlinear model better fitting the actual working characteristics of the double-capacity water tank liquid level control system. 本发明公开了一种双容水箱液位系统动态特性建模方法、系统及存储介质，模型在被实际应用之前所有相关参数通过合适的参数辨识方法被辨识出来，减小了在线参数辨识对控
