Subsequently, the correction factor is injected into the original combination vector to form a disturbance enhancement input. This rhythm synchronization driven data reconstruction path has a dynamic adjustment path with cross-period prediction balance capability, and constitutes the core calculation model of the rhythm feedback mechanism.

[0115] It should be noted that for the formula structure involved in the present scheme, the dimensionless item can be used as a proportional or structural adjustment factor. When combined with quantities with units, it only plays a numerical scaling role and does not introduce new physical dimensions, so it will not change or confuse the unit system of the overall expression. Such a combination of "dimensionless items and quantity unit items" can be understood as a composite structure expression commonly used in mathematical and physical modeling, which conforms to the principle of dimensional consistency and has a clear physical interpretation basis.

[0116] Secondly, in the formula structure of the present scheme, if multiple variables with different physical units are involved, including but not limited to time, mass or energy variables, their joint occurrence is to express the cooperative modeling relationship of multiple physical mechanisms. Each variable can be mapped by a function, combined by a ratio, or adjusted by a normalization to form a unified structure. The unit is clear and the meaning is clear. The overall expression conforms to the principle of dimensional consistency and the common norm of engineering modeling.

[0117] If the design constant, weight, adjustment factor, threshold parameter, proportion coefficient and the like in the scheme are adjusted, they are the adjustable control parameters for different application environments, and their values depend on the target device configuration, data input characteristics and performance optimization target, and are set within a reasonable range through model verification, performance constraints or engineering calibration in the implementation stage. Although such parameters do not have a unique value, they have a clear adjustment logic and calculation path, and belong to the deterministic setting process in engineering implementation. The purpose of such setting is to ensure that the scheme has both general adaptability and reproducibility and operability, and does not affect its technical clarity and implementability.

[0118] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
