Design of active noise control using feedback control techniques for an acoustic duct system

The design of active noise control (ANC) using feedback control techniques for a one-dimensional acoustic duct system is explored. The complex-value-based mathematical model of the total system is developed and verified. The sensitive parameter-acoustic terminal impedance is estimated using the system identification method. The ANC design is formalized into a set of standard control design problems with respect to specific requirements. Some simple PID controllers are developed for the considered ANC system. The simulation and test results show a bright potential to use feedback control techniques for a simple but efficient ANC design.
