| 摘 要： | 研究了非线性比例导引系统的性能。利用一种单输入双输出二阶非线性状态估计器估计弹目视线角速度和角加速度，状态估计器的输入直接采用来自导引头的信息，其输出量可以给出弹目视线角速度和角加速度的估计值，将此估计量作为补偿信号引入到比例导引系统中，形成了非线性比例导引系统。仿真研究表明，这种非线性比例导引具有良好的制导特性。

| Abstract: | The character of proportional navigation with a nonlinear estimator is studied in this paper. A nonlinear second order estimator with single input and double outputs is introduced to estimate view angular velocity and angular acceleration of missile and target. The seeker's output is used for the estimator input directly. The output from the estimator is used for target maneuvering estimation. This estimator is introduced into proportional navigation system to form nonlinear proportional navigation system. The simulation results show that this nonlinear guidance system has superior properties. |
