微分环节 meaning in English

derivative element
differentiator

By using transfer function , quantitative analysis , pattern analysis and reduced analysis of driving fatigue can be finished . based on automatic control theory , driving fatigue can be analogized as two parts : inertia link and proportion differential link
采用传递函数将驾驶疲劳定量化、简约化、模式化，借用自控理论将驾驶疲劳类比为两个过程：类惯性环节的响应过程及类比例微分环节的响应过程。
Contraposing the controller made up of fixed - plus proportion and intelligent integral can not achieve the expectant dynamic and static characteristic , the control strategies of seasoned manipulators are simulated in different phases of step response curve of the system , a nonlinear pid human - simulated intelligent control algorithm is presented by importing p , nonlinear i and fixed - plus d into human - simulated intelligent control
摘要针对仿人智能算法中，由固定增益的比例和智能积分组成的控制器不能获得满意的动静态控制性能的缺点，在系统阶跃响应曲线的不同阶段，模拟了经验丰富的操作人员的控制策略，将非线性比例环节、积分环节和固定增益的微分环节引入到仿人智能控制中，提出了一种非线性pid仿人智能控制算法。
