Abstract
The effectiveness of random-switching control, by which the switching-noise spectrum is spread and its level is reduced, is revealed analytically. The noise spectrum generated by random switching is analyzed by a general approach that uses a noise-generation model and a switching function with a random process. In the analysis, it is shown that the region where the noise spectrum is sufficiently reduced can be expressed in terms of the standard deviation of switching interval. The validity of the analysis is confirmed by using the normal distribution instead of the actual distribution
