Research on frequency characteristic test method of servo mechanism based on schroeder phased harmonic signal

Research on frequency characteristic test method of servo mechanism based on schroeder phased harmonic signal

The traditional frequency response test mainly adopts the sweep frequency sinusoid signal testing method, which has high accuracy, but takes a long time. This paper introduces the basic theory of the Schroeder Phased Harmonic Signal (SPHS) testing method. The comparison experiment is conducted on th...
