| Summary: | 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 the servo mechanism of a certain missile, and the accuracy and rapidity of the SPHS testing method are verified. Finally, according to the experiment data, the threshold standard of SPHS parameters is put forward, which provides a reference for selecting the SPHS parameters in the frequency response test of servo mechanism. |
