查询词典 angle brick

Then, aerodynamic parameters in different flight conditions are used to imitate the uncertainty of the system, and the digital simulation of closed-loop system designed is performed. The results show that the system can accomplish asymptotic decoupling of roll angle, sideslip angle and head-on angle for aircraft, and the system is provided with the function for restraining uncertainty in the system. This illustrates that the flight control system designed has not only good decoupling characteristic, but also better robustness.

然后用不同飞行条件下的空气动力参数变化来模拟系统的不确定性，并进行闭环系统数字仿真，结果表明，所设计的控制律不仅可实现对飞机滚转角、侧滑角、迎角等的渐近解耦控制，而且对系统不确定性具有较强的抑制作用，说明系统具有较好的解耦性和较强的鲁棒性。

The system can automatically seek north when the vehicle is immobile. And the time consumption is no more than 5.5 min. Besides, the system can keep azimuth angle and provide tilt angle and pitch angle of the vehicle.

Firstly, the control of reentry phase and the model of RCS jets are presented. Then the flight control system is divided into two subsystems based on the time-scale separation principle. The fast states subsystem corresponds to the three body-axis angular rates, the slow states subsystem controls the angle-of-attack, sideslip angle and the rate of the bank angle about the velocity vector. Lastly, the proportional-plus-integral feedback is designed to increase the system robustness.

首先，分析了SRLV再入段的数学模型，并给出了反作用推力控制系统的控制模型；其次，将非线性动态逆方法与时标分离原则相结合，考虑飞行器姿态控制系统的外环角回路的慢变特性和内环角速度回路的快变特性，独立设计了两个回路的控制律；最后，为了增强系统的鲁棒性，分别在两个回路中引入了比例－积分反馈，有效地抑制了干扰力、力矩和非线性对消带来的逆误差。
