摘要:
本文提出了一种结合前馈和反馈麦克风策略的电声吸收器声阻抗控制架构,应用于电流驱动扬声器。前馈系统能够实现良好的直接阻抗控制,但所需执行器模型的不准确性可能导致被动性丧失,从而引起不稳定行为。反馈贡献使吸收器能够更好地处理模型误差,并仍能实现精确的阻抗,保持被动性。数值和实验研究用于比较这种新架构与最先进的前馈控制方法。
英文摘要:
This paper presents an acoustic impedance control architecture for an electroacoustic absorber combining both a feedforward and a feedback microphone-based strategies on a current-driven loudspeaker. Feedforward systems enable good performance for direct impedance control. However, inaccuracies in the required actuator model can lead to a loss of passivity, which can cause unstable behaviors. The feedback contribution allows the absorber to better handle model errors and still achieve an accurate impedance, preserving passivity. Numerical and experimental studies were conducted to compare this new architecture against a state-of-the-art feedforward control method.
