derivative time meaning in Chinese

微分时间

Through simulation and calculating the four models , the influence on proportion coefficient , integral time constant , derivative time constant and partial feedback coefficient for system performance is analyzed . the ideal reference value of every parameters and step respond curves are given . the simulation result may be used as reference for making analogue controller or digital controller
通过对这四种模型的仿真研究，分析了各模型中比例系数、积分时间常数，微分时间常数及局部反馈系数对系统性能的影响，并给出了各参数较为理想的参考值及阶跃响应曲线，仿真结果对制作模拟控制器及数字控制器有一定的借鉴作用。
