Abstract

This paper presents an headphone ANC system with dual feedback control. It consisted of a speaker, two microphones, and two controllers to attenuate the ambient noise at microphone. The benefit of two controllers is that the control performance and stability of the system are improved. The lack of single controller can be compensated by another controller. Since the two feedback controllers affect two microphones mutually, the design of these two controllers is not easy. An H2-norm optimization problem is introduced to find out the optimal controllers to meet the specifications. The whole system is well investigated and the simulation shows the effective of the optimization method.
