Abstract:

When designing active control systems to reduce noise radiated by vibrating surfaces, there are many variables that need to be optimised to achieve the maximum possible system performance. There are also a number of hardware and software aspects that must be considered and accounted for when a laboratory system is adapted for operation in an industrial or commercial environment. There needs to be some sort of hierarchy in the approach to optimising the many variables which include type, locations and numbers of control sources, quality of the reference signal for feedforward systems, software structure and algorithm considerations and hardware architecture considerations. This paper will discuss a number of issues associated with the implementation of active noise and vibration systems that have been the subject of investigation at The University of Adelaide.
