摘　　要：主动控制技术在飞机设计中的运用可以提高飞机的性能并带来较大的收益。放宽静稳定性是主动控制技术中最重要的功能。本文介绍了放宽静稳定性技术、实现途径和放宽程度分析,归纳了静稳定度放宽后对飞机带来的影响。最后,研究了放宽以后的增稳方案,并以A300为例进行了放宽前后的增稳仿真。仿真结果说明了放宽静稳定度以后,通过增稳可以实现稳定性的补偿。经过增稳设计后,放宽静稳定性的飞机完全可以达到放宽前飞机的稳定性。Using active control technology in aircraft＇s design can improve the performance of the aircraft and generate great returns. Relaxed static stability is the most important functions of active control technology. Firstly, the concepts and principles about relaxed static stability are introduced. Then the reference standards for the choice of the relaxation degree and the influences resuhed from relaxation are summarized. Lastly, the stability augmentation programs are studied. And carrying out simulation on stability augmentation of the A300 before and after relaxing static stability. The results of the simulations show that stability compensation can be achieved by stability augmentation. Through stability augmentation, the stability of the aircraft after relaxation can be achieved as good as the original aircraft＇s.
