    Abstract

    An analogue filter is a basic building block in the feedback controllers for active noise control. Usually, such filters are designed case by case for each application. Using second-order filter blocks and constrained optimisation, feedback control filters can be designed in a more general level and application-independently. The goal for the optimisation is to minimise the error signal of the closed-loop system, and the constraints are set by the stability criteria of feedback systems. All combinations of the filter blocks are formed and optimal parameters for each filter topology are computed. The optimisation procedure is described and simulation results are shown.
