Abstract
En 中文
• A real-time experimental implementation of constrained MPC for tonal Active Noise Control in acoustic ducts is presented. • The MPC formulation explicitly enforces actuator, slew-rate, and output constraints without relying on signal clipping. • Compared to FxLMS-based approaches, MPC achieves faster transients and avoids windup-induced spectral distortion under constraints. • Frequency-domain analysis shows that constrained MPC produces a spectrally pure control signal with minimal broadband leakage. • The proposed controller is shown to be computationally feasible for real-time operation with a high-order prediction model.
