本文提出了一种H/sub 2//H/sub /spl infin// feedback控制器的设计，用于头枕的主动声控制。该设计方法采用H/sub 2/性能准则，并带有H/sub 2/和H/sub /spl infin//约束，利用FIR Q参数化和频率离散化将其转化为凸规划问题，并采用序列二次规划求解。设计方法被认为是有效的，因为各种目标和约束，这是有用的，这种主动声控制应用程序很容易被包括在内。然后，一个实验头枕系统的鲁棒控制器的设计，性能，鲁棒稳定性，和乘法的植物不确定性模型的设计和分析。然后在数字信号处理系统上实现了降阶实时控制器，产生了设计中预测的性能。
This paper presents an H/sub 2//H/sub /spl infin// feedback controller design for active sound control in a headrest. The design method which employ an H/sub 2/ performance criterion, with H/sub 2/ and H/sub /spl infin// constraints, was formulated as a convex programming problem using FIR Q-parameterization and frequency discretization, and solved using sequential quadratic programming. The design method was found effective since various objectives and constraints which are useful for this active sound control application were readily included. A robust controller was then designed for an experimental headrest system, and the performance, robust stability, and the multiplicative plant uncertainty model used in the design are presented and analyzed. A reduced-order real-time controller was then implemented on a digital signal processing system, producing the performance predicted in the design.
