用复合控制把惯导系统测量的炮塔俯仰转动角速度（扰动角速度）反馈到控制前端，进行预先补偿，可保证小的瞬态误差和系统的稳定性。
The stability and small dynamic errors could be confirmed by using the method of composite control in which the pitch angular rate of barbette sensed by INS was feed back and compensated in advance.
同时采用小扰动法推导了俯仰通道和滚动通道的简化模型，为空气动力和姿控发动机推力复合控制系统进行初步设计提供了依据。
What′s more, according to the method of little disturbance, the simplified model of pitching and rolling plane is derived, so preliminarily combined control system can be designed.
同时，文中还对目前尚未解决的复合电能质量扰动分类问题进行了初步的探讨。
Furthermore, classification of complex power quality disturbances which has not been resolved is discussed in the thesis.
