摘要：
本文采用描述函数法分析微分器的特性和参数选择。非线性微分器是对线性微分器的有效补偿，而由线性和非线性部分组成的混合微分器结合了线性和非线性微分器的优点。混合微分器的优点包括结构简单、始终快速收敛以及有效抑制噪声。通过实例验证了该方法。
英文摘要：
In this paper, describing function method is used to analyze the characteristics and parameters selection of differentiators. Nonlinear differentiator is an effective compensation to linear differentiator, and hybrid differentiator consisting of linear and nonlinear parts is the combination of both advantages of linear and nonlinear differentiators. The merits of the hybrid differentiator include its simplicity, rapid convergence at all times, and restraining noises effectively. The methods are confirmed by some examples.
