A New Optimal Guidance Law For Intercepting Maneuvering Objects

摘要

In order to achieve a new minimum energy interception of an arbitrarily maneuvering vehicle a nonlinear model is first approximated by a series of local linear models using an on-line linearizing method for some state vari- ables, and then from the derived local linear models a new optimal strategy is developed using the receding horizon concept and associated techniques. That evader maneuvering in a small scope can be dealt with by the corresponding local linear model, and its maneuvering in a large scope is handled by model switching among a series of local linear models. Simulation results show that the system designed in this way can intercept a randomly maneuvering evader.
