The Application of Spline Function in System Frequency Domain——A Practical Analytic Method of the System Dynamic Response(II)

LI She-gen

Abstract

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.
