摘要
自动控制系统的动态性能的分析方法包括时域分析法,频域分析法,及稳定性判据。具体的分析法有微分方程,传递函数,方框图,伯德图,奈奎斯特图和根轨迹等。对数频率特性法是频域分析中应用较为广泛的一种。文章从自动控制系统的动态性能分析方法入手,着重探讨了样条函数在系统频域分析中的应用,并举例加以说明。
Methods of analyzing the dynamic performance of automatic control system can include time domain analysis,frequency domain analysis and stability.There are derivative equation,transfer function,block diagram,Bode diagram,Nyquist diagram and root-locus method as the specific analytical methods.Log frequency characteristic is widely used in frequency domain.The article sets about dynamic performance analysis of the automatic control system,discusses the analysis of the spline function in system frequency domain,then gives examples to explain it.
