摘　　要：由潜艇动力机械周期振动引起的辐射噪声是潜艇隐蔽航行的主要噪声源,在频域中表现为中低频多根分立的线谱,严重影响潜艇的声隐身技术性能。针对潜艇动力机械隔振系统存在的多根线谱问题,提出混合隔振系统逆解耦的多线谱控制方法。系统阐述混合隔振系统逆系统的构建方法、逆系统解耦的结构以及逆系统解耦后附加控制器的设计方法。最后,给出一个设计实例并进行仿真计算,结果表明基于逆系统解耦的方法能够有效的降低系统中存在的多根线谱。The radiation noise induced by periodic disturbances from the power plant of the submarine is the main noise source for stealing cruise of the submarine. Its performance shows a multi-line spectrum in the low and intermediate frequency bands, which may seriously deteriorate the stealing performance of the submarine. In this paper, a new method for multi-line spectra control based on reciprocal decoupling was proposed. The existence of the reciprocal system of the hybrid vibration isolation system was analyzed. The model of the reciprocal system was built. And the reciprocal decoupling control of the system was designed. Finally, a design and simulation example was presented. According to the results of simulation, it was found that the hybrid vibration isolation system can be controlled by the reciprocal decoupling control algorithm. Moreover, the performance of the hybrid vibration isolation system was much better than the passive system.
