Abstract: The command‑FxLMS algorithm for multi‑order noise modulation has unnecessarily high output gain when there is a phase error between the command signal and the disturbance signal. Aiming at this problem， a multi‑order active sound profiling system based on the modified differential phase scheduled command filtered‑x least mean square （DPSC‑FxLMS） algorithm is constructed. By adjusting the phase of the command signal to keep it in phase with the disturbance signal， the output level of the control signal is reduced while keeping the same control performance. Simulation analysis and comparison of engine steady‑state multi‑order noise modulation using the above algorithms are carried out， and the control effect of the algorithms is verified. For the in‑phase case， two algorithms share the identical performance and control effect， while for the out‑of‑phase case， the DPSC‑FxLMS algorithm requires less control effort than the command‑FxLMS to achieve the same control performance. The multi‑order noise modulation simulation of the above algorithm is carried out using the multi‑order noise signal collected from a real vehicle. The simulation results validate the feasibility of the proposed algorithm for practical in‑vehicle applications.
