Abstract :
In this paper, stability studies of a multiple channel active noise control system are approximated in terms of multivariable state space function. By considering the presence of the acoustic channel, a multiple channel filtered x LMS adaptive notch filter is used with a specified plant model. It has been shown that the system behaves as a linear time-invariant system with a flow adaptation. The convergence coefficient and the estimation error of the plant phase characterize the behavior of the system
