9313764 Chait This research project deals with the development and extension of the standard Quantitative Feedback Theory (QFT) diagonal controller design to non-diagonal controllers for multiple-input, multiple-output systems. The methodology incorporates the interaction effects between control design at each sequential loop closure in multiple loop systems, and emphasizes these effects in terms of the gain and phase margins of the closed- loop transmission. The efficacy of the techniques to an active noise control experiment in a three-dimensional asymmetric cavity. The apparatus represents highly coupled transfer function matrix from speakers to microphones, lightly damped resonance frequencies in the three-dimensional acoustic space, and uncertainty in modeling and identification of the transmission between speakers voltage and microphone sound pressure levels. The research results provide a more effective design tool compared to those currently available. ***

9313764 Chait本研究项目涉及多输入多输出系统的标准定量反馈理论（QFT）对角控制器设计到非对角控制器的开发和扩展。该方法结合了多环系统中每个顺序闭环控制设计之间的相互作用，并强调了闭环传输的增益和相位裕度方面的这些影响。在三维非对称腔体中进行了有源噪声控制实验。该装置表示从扬声器到麦克风的高度耦合的传递函数矩阵、三维声学空间中的轻度阻尼的谐振频率、以及扬声器电压和麦克风声压级之间的传输的建模和识别中的不确定性。 研究结果提供了一个更有效的设计工具相比，目前可用的。 ***
