摘要

Power spectral density (PSD) with peakedness (100) with both simultaneous control, the random signal is formed and it is the system and method in order to control, the signal which is controlled is measured from transducer, PSD (111) is converted fast Fourier transform (FFT) of making use. As for measurement PSD (117), the adaptation filter (119) it is renewed in order to revise concerning error standard PSD (121) with by comparison. Peakedness of the measurement data is calculated simultaneously and (125), standard peakedness (123) with is compared. The closed-loop control loop (127) of making use, you adjust the peakedness of the white noise random generator variable peakedness (101) with. This white noise furthermore the filter is processed the adaptation filter (119) by, offers the output signal which is used in order to drive control processing. Selective figure Figure 1
