| Abstract: | The basic theory of the second order sliding mode tracking differentiator was introduced, and its frequency characteristic was analyzed by describing function. On this basis a band-pass filter was designed andits frequency characteristic was analyzed. The methods for choosing and adjusting the parameters of the second order sliding mode tracking differentiator and the band-pass filter were summarized. Simulation results showedthat, if proper parameters were chosen, the band＇pass filter would select the required signal with specific frequency from the compounded signals. |
