Abstract :
The stability and convergence speed of a narrowband controller based on a delayed-X LMS algorithm are studied. The stability limit is computed using the Nyquist criterion. The response envelop is obtained from a baseband model of the system and the optimal gain which minimises the convergence time is derived.
