| Abstract: | The optimum design of the controller of compound active noise cancellation earmuff is discussed. The deduction of objective function, the decision of restriction and the chosing of optimizing method are specially discussed with the example of second order feedback controller. Some problems in the optimum design, such as the peaked effect of noise cancellation and the unstability of special frequency, are analysised, and the solving methods are introduced. The experimental results are compared to the theorically calculated effects, so that the effectivity of optimum design is testified. |
