| 초록 |
To evaluate hardware, software, and the performance of the road noise active control system prior to conducting the actual vehicle test, a HIL(Hardware-In-the-Loop) simulator was proposed. Reference signals and primary noise signals were measured by accelerometers and microphones on the test vehicle, respectively. The secondary path, which was used for the plant model in the simulation loop, was also modeled in the test vehicle. Various references and noise data could be stored on the host PC of the HIL simulator, and optionally used for simulations. The HIL simulator hardware was developed by using a multicore, system-on-chip processor configured with TMS320C66x CorePac DSP. This multi-rate system is composed of the sampling rate conversion blocks for input and output signals. The control signal of the active noise control system was then convolved with the secondary path model, and a residual error signal was produced with the addition of the primary noise. The proposed system was verified in terms of convergence characteristics, while noise reduction performance was evaluated after comparing the MATLAB simulation with the actual vehicle test. |
