伺服控制系统跟踪任意输入函数的研究

为了使设计指标能保证伺服控制系统准确地跟踪任意输入函数，研究了一种基于对收敛傅里叶级数响应的分析方法：以任意输入函数能满足傅里叶级数展开条件为前提，将输入函数以奇函数形式展成满足误差要求的有限项傅里叶级数，推证出稳定线性定常系统对该三角级数的响应，确定了输入函数频谱特性与系统频域误差的关系，给出了频域内系统能跟踪任意输入函数的设计指标。

Study on Servo Control System Tracking Arbitrary Input Function

In order to accurately track the arbitrary input function, an analysis method forthe response to couvergent Fourier series is studied. Based on the satisfying to the unfoldingcondition of Fourise series, the input function is unfolded to the limited item Fourise series ofsingular function in the error range. The relation between the frequency characteristic ofinput function and the frequency domain error of system is determined. The design indicatorsof the system tracking arbitrary input function is given.
