| Abstract: | In this paper feedabck control structure (FBCS) and feedforward control structure (FFCS) are compared based on the active noise control (ANC) theory Then a method of the actual system of feedback adaptive active noise control using asymptotic hyperstable method of MRAS is presented Implementation scheme of active noise-reduction based on feedback structure is proposed The experimental results show the obvious noise cancellation effect of the system |
