Length Variation Effect of the Impulse Response Model of a Secondary Path in Embedded Control

Figure 6

Comparison of narrowband sweep real-time control performances in terms of error spectra and attenuation between before control (thick lines) and after control (IRF length = 30: dotted lines, = 63: thin lines, and = 93: thick dashed lines). (a) Error PSD. (b) Attenuation.
