ANC in the small cavity using CDM

For active noise control system, one would choose one of two methods: Fixed control design and Adaptive filter design. Each one has its own advantages. But fixed controller design method prefer for active noise control in a small cavity system. In this paper, we design a controller for the small cavity system using CDM and compare controller using CDM with $H{\infty}$. The order of the resulting controller is lower than that of the robust $H{\infty}$ design, which means CDM will be more prefer for implementation purpose designs.
