本文研究了旋转轴系统加速度区惯性力矩建模方法的建立。通过测量角速度获得估计的加速度和转动惯量轴的变量，用于计算惯性力矩。所评估的动态机制是角速度水平（间隔）之间的加速度斜坡，其使用耦合到AC电机的变速驱动器来实现。本文重点评估信号处理中的主要参数，如速度信号的推导、数字滤波器和数据平滑方法的应用，以及它们对所生成的扭矩曲线中感兴趣的主要特征的影响，如峰值扭矩幅度、上升和下降斜率、稳定性和可重复性。采用定性方法确定测量不确定度的贡献。因此，加工方法的验证方法和提出的物理原理是可行的。
This article studies the setting of the method to model the inertial torque in the acceleration regimes of a rotating axis system. The angular speed measurement to obtain an estimated acceleration and the moment of inertia axis of the variables are used to calculate the inertial torque. The evaluated dynamic regimes are acceleration ramps between levels (intervals) of angular speed, which are implemented using variable speed drives that are coupled to AC motors. The article focuses on assessing the main parameters in signal processing, such as the derivation of the speed signal, application of digital filters and data-smoothing methods, and their effects on the main features of interest in the generated torque curves, such as the peak torque amplitude, ascending and downward slopes, stability and repeatability. A qualitative approach was performed to identify the measurement uncertainty contributions. Thus, the validation methodology of the processing methods and the proposed physical principle are feasible.
