The problem of active structural acoustic control in an enclosure using radiation mode is investigated. The response of the coupled enclosure is derived in terms of radiation modes. The potential energy in the enclosure can be decomposed into independent parts and the radiation modes contribute to potential energy independently. The control strategy for minimizing first G radiation modes with large radiation efficiency is proposed, and the optimal model of control forces is presented. Finally, a numerical simulation for minimizing sound transmission into a rectangular enclosure using the proposed method is conducted. Simulation results indicate that one control force can control one radiation mode and controlling the first four-order radiation modes with four control forces can achieve significant potential energy reduction at the low frequency range.
基于Matlab/Simulink/dSPACE开发了四轮转向(4WS,Four-wheel Steering)车辆控制系统的硬件在环仿真(HILS,Hardware In the Loop Simulation)快速开发平台。在此平台的基础上,利用HILS技术实现了各控制算法鲁棒性能的评价和实际车辆执行电机死区的控制,结果表明基于μ综合鲁棒控制方法有较好的综合性能。因此设计开发的4WS硬件在环仿真开发平台为先进控制算法的分析与设计、开发和评价及ECU的开发提供理论指导和技术支持。
