Abstract
Reduction of noise in a car cabin due to road irregularities has been a subject of research for many years. For reducing such noise, we proposed H2-based active structural acoustic control method that used a road noise estimation model and we verified its feasibility on a test bench. In this paper, we propose a road noise reduction control method in driving condition. The structure of the control system, the method to design actuator allocation, and the generalized plant and weighting functions for MIMO H2 controller synthesis are proposed. The proposed methods were verified in the computer simulation results and the driving experimental results.
