technical field [0001] The invention relates to a method for automatically constructing a dynamic model of an intelligent contactor, in particular to a method for automatically constructing a dynamic model of an intelligent contactor based on a neural network. Background technique [0002] The research of contactor intelligent control technology is inseparable from the support of dynamic simulation. Dynamic simulation can reflect the interaction relationship between electricity, magnetism and force in the whole process of contactor starting, holding and breaking, and provides a basis for determining the control method. in accordance with. The complexity of the dynamic characteristics of contactors is not only reflected in the distribution of magnetic circuit parameters and the nonlinearity of magnetization characteristics, but also in the mutual coupling between electricity, magnetism and force. At present, the dynamic simulation of contactors mainly includes magnetic circui...

Problems solved by technology

[0005] The above simulation methods all need to construct a geometric model of the contactor, and then load the characteristic parameters of electricity, magnetism, and force of the material used for dynamic calculation. The process of building the model is relatively complicated, and a large number of simplifications are often used in the construction process, making the simulation accuracy difficult. Guaranteed, the construction process is heavily dependent on the body parameters of the contactor, resulting in the need to re-model different types of contactors, the workload is heavy, and the versatility is not strong
