Abstract: In order to improve the development efficiency of digital power supplies,TI has developed a software frequency response analyzer (SFRA) tool for C2000 series processors to test the frequency characteristics of digital power supplies.Based on the analysis of the SFRA principle and the application requirements of AC servo system,in this paper,SFRA is applied to the frequency characteristic test of AC servo system.Experimental results show that the SFRA method can also be used in the AC servo system.On the one hand,it saves the cost of the system.On the other hand,it expands the application scenario of the method and has positive research value.

Key words: AC servo system, Frequency characteristic test, Frequency domain identification, SFRA
