侧窗探测下的姿态变结构控制

为解决导引头视场受到侧窗限制的问题,给出侧窗视场范围和拦截器姿态角之间的约束算法,并针对侧窗探测条件下弹体姿态控制的要求,用变结构控制方法实现姿态角的跟踪,并对抖振问题给予解决办法。在变结构控制器参数的选择上加入自适应参数选择环节,经过仿真,系统能够快速跟踪期望姿态角,跟踪的精度高。

Attitude variable structure control for side window detection

In order to solve the problem that infrared-guided seeker is restricted by side window vision scope,the restriction arithmetic between side window vision scope and attitude was put forward.And according to the demand of missile attitude control with side window detection,the control of attitude angle using variable structure controller was carried out and the vibration problem was solved.In the process of selecting variable structure control parameter,adaptive parameter selecting program was added.The simulation result shows that the system can track expectable attitude angle rapidly with high accuracy.
