The characteristics of the projectile and three loop autopilot instruction formation characteristics were analysed. From equivalent pitching angle of lateral acceleration feedback loop  combined with the instruction of generalized error  autopilot structure was simplified  and three loop autopilot adaptive control law and stability were designed. The test data show that when disturbance torque was 600Nm  the attitude angle generalized error was -4.4. In the time lasted about 15s  late trajectory accuracy was within 1.0.Three loop autopilot adaptive control law was able to control the disturbance of initial trajectory and adapt to dynamic characteristics changes  control system stability. It was the initial trajectory accurate solution method of flight. 2011 IEEE.   Weak solution to pressureless type system 期刊论文  OAI收割 COMMUNICATIONS IN PARTIAL DIFFERENTIAL EQUATIONS, 2005, 卷号: 30, 期号: 1-3, 页码: 283-304 作者:  Huang, FM   |  收藏  |  浏览/下载：10/0  |  提交时间：2018/07/30 delta wave  generalized characteristics  generalized potential  pressureless type sysetm
