Background technique [0002] Parameter design is an important link in the design process of electromagnetic relay products. It not only directly determines whether the output characteristics of the product can meet the design requirements, but also directly affects the uncertainty factors such as external interference, internal interference, and manufacturing dispersion of the product design scheme. Resistance, that is, robustness. Therefore, it is of great significance to improve the performance stability and consistency of electromagnetic relay products by adopting a reasonable quality consistency design method to effectively control the design parameters. [0003] The key to design parameters is to use the nonlinear nature between input parameters and output...
