一种导弹末制导自适应控制方法

An Adaptive Control Method for Missile Flight in Terminal Guidance

文中根据导弹响应快和精度高的基本要求,在导弹变向跟踪接近目标时,对导弹制导控制过程中的控制方法进行研究和数学推导,提出了一种导弹末制导的自适应控制方法,该方法提高了导弹马赫数和质量在较大范围(35%)内变化时系统的响应精度和稳定性。将该方法应用于导弹跟踪飞行控制,通过计算机仿真,结果比较满意。

With the demand of quick respond and precision for missile flight in terminal guidance, an adaptive nonlinear controller is designed that guarantees tracking performance when the uncertain parameters vary within stability bound. In order to achieve asymptotic tracking, adaptation is introduced to enhance closed-loop robustness, while mach number and mass changes with 35%. Computer simulations show that this approach offers a possible autopilot design for nonlinear missiles with uncertain parameters and the results are satisfaction.
