*3.2. Power Feeding Rate Model*

3.2.1. Single-Variable Regression Model

Taking the real-time power consumption of each key operating component in the maize silage harvesting process as the input of the model, a one-dimensional linear regression model between the single power data and the feeding quantity is established, as shown in Formula (15).

$$\begin{cases} \ q\_m = a + b\mathbf{x} + \varepsilon\\ \varepsilon \in N(0, \sigma^2) \end{cases} \tag{15}$$

where *qm* is the feeding rate of the silage harvester. *x* represents the power of a key component. *a* and *b* are model regression parameters. *ε* is residual in the single regression.
