一种非最小相位导弹过载控制系统设计方法研究

Study of a Non-minimum Phase System on Missile Overload Control

针对导弹过载控制的非最小相位系统特征,提出了一种以滑模面作为输出的滑模控制方法,该方法以反演设计和输出重定义相结合,并且通过李雅普诺夫稳定性理论证明了该方法的理论可行性。最后利用某型导弹的过载数学模型进行了数字仿真,仿真结果证明了该控制系统设计方法的有效性。

A method which defines the sliding surface as a new output has been put forward for a non-minimum phase system of missile overload, in which the methods of backstepping and output-redefinition are combined. Then Lyapunov stability theorem is used to prove the correctness of the design method. Finally simulation for missile model on overload is made, and the results have shown the correctness and effectiveness of the method.
