自然稳定性 meaning in Chinese

natural stability

Form the practical engineering point of view , the longitudinal natural stability of anti - submarine helicopter is analyzed , the stabilized loop of the pitch angle is systematically studied . this paper is mainly on the design and simulation of the stabilized loop of pitch angle with classic control method and fuzzy control method and many useful results are achieved . the main work of this paper can briefly described as follows : after the mathematical models of aircraft was build with relevant date , the stabilized loop of pitch angel was designed and simulated
本文从工程应用的角度出发，分析了国产直九c反潜直升机的纵向自然稳定性，分别应用古典控制和模糊控制的方法，系统地研究了国产直九c直升机的纵向姿态角稳定回路、速度回路、高度回路、自动过渡等，对纵向姿态角稳定、速度、高度、自动过渡回路进行了控制律的设计与仿真，取得了良好的控制效果。
