The scheme also adopts tracking differentiator to filter the signal.
并采用跟踪-微分器对信号进行了滤波。
Meantime, differential signal is distilled by nonlinear tracking-differentiator instead of the method of difference, which improves the quality of differential signal.
同时用非线性跟踪-微分器代替差分法来提取微分信号，提高了微分信号的品质。
The auto-disturbance rejection controller is composed of three parts: tracking-differentiator, extended state observer and nonlinear state error feedback control law.
自抗绕控制器由三部分组成：跟踪微分器、扩张状态观测器和非线性状态误差反馈控制律。
