非线性跟踪微分器 稳态性能 无差度 nonlinear tracking-differentiator steady-state performance indiscrimination degree
摘要
针对非线性跟踪微分器无法实现对所有输入信号的无差跟踪问题, 研究3种不同形式跟踪微分器的稳态性能.通过分析抑制函数的特性和典型输入情况下系统的稳态误差, 确定其适用范围, 并对推论结果进行验证.仿真实验表明, 非线性跟踪微分器为一阶无差系统, 只能实现对阶跃输入信号的无差跟踪.
Abstract
Considering the problem that the nonlinear tracking-differentiators(NTD)cannot track all the in-put signals without error, the steady-state performance of the nonlinear tracking-differentiators in three different forms was discussed.The applicable scope of NTD was determined through analysis the characteristics of re-strain function and steady-state error in typical input, and the deductive results were verified in simulation.The results show that the nonlinear tracking-differentiators are first-order indiscrimination systems which only can track the step signal without error.
