Abstract
One of the main components for real applications of
Active Noise Control is the controller. This is
especially true for centralized, cross-coupled
multi-channel systems. Such systems are often used for
Active Noise Profiling (ANP). In ANP, usually only
periodic noise components are processed to change the
audible psychoacoustic profile of the target system.
Multi-channel ANP controllers have this far been
sophisticated and expensive laboratory units, and the
development of their algorithm has been a challenging
task. To address these challenges, a multi-channel ANP
controller with associated user interface has been
developed. The whole development cycle of the controller
is based on a simulation model. The functionality of the
controller can be simulated before actual implementation.
The parameters and structure of the developed embedded
software for the target hardware controller may thus be
easily adjusted. Also, the same user interface is used
both with the controller model and the final target
hardware. Furthermore, a cost-effective multi-channel
analog interface has been developed for the controller,
as well as related simulation models for it. For
successful future product realizations of the ANC and
especially ANP products the effective and flexible
controllers are the key components. Both the controller
development cycle and the hardware issues must be
addressed to achieve this. The proposed approach presents
a road map for such development steps.
