| 摘 要： | 为了抑制微分器噪声输出和提高信噪比,文中列出了几种微分器的数值算法,并进而总结为一个计算公式。根据模拟电路经离散化得到的脉冲传递函数,既可作为带有低通滤波性能的微分器,又可作为微分状态估计器。本文所述的微分器无论在结构、计算速度等方面均优于一般状态空间方法设计的状态估计器。

| Abstract: | Several algorithms for differentiation are evaluated to suppress the noise output of signal, and pulse transfer functions from analog circuits are used to estimate derivatives of signals for feedback purposes in control applications. The effect of noise, filtering, computation speed and derivative estimator characteristics are discussed. Compared to the standard state estimator approaches, the derivative approaches presented are superior and less complicated in many applications. |
