Abstract

In this paper, we developed the evaluation system for the active noise control so that the algorithms can be easily evaluated in real-time on the system. We implemented the active noise controller based on a single-chip with only additional op-amps for signal conditioning because the TMS320C280049 MCU includes almost all necessary peripherals for the active noise controller. Due to the difficulty in testing algorithms on embedded-type hardware unlike in computer simulation, we also developed GUI-based evaluation software which makes it simple to test algorithms on the hardware. Using the GUI software, we can optimize the parameters of the algorithms with ease in a specific noise environment because the parameters can be adjusted in real-time when the algorithm is running on the hardware.
