In this paper we carried out the simulation for controlling the resonance frequency of a Helmholtz resonator, which is used for the reduction of noise. The resonance frequency is designed to the desired value by PID control of the acoustical boundary condition of the Helmholtz resonator. The resonator like this is called Smart Helmholtz Resonator. At first the gains of PID controller is changed to several values and it is confirmed that the resonance frequency is varied. In order to realize the desired resonance frequency, the gains of PID controller are determined by the response surface method. By using the response surface method the determination of the optimal gains are possible for a lower frequency region accurately. It is shown that this method is effective for designing the resonance frequency of Smart Helmholtz Resonator.
