Abstract

To solve the problem of intercepting target with missiles for forward tracking, this paper proposes a novel forward tracking guidance algorithm based on adaptive fast dynamic surface sliding mode control method for interceptor missiles. Firstly, the guidance system model of forward tracking intercept is established based on the relative motion relation of missile-target and forward tracking interception principle. Secondly, in order to deal with the uncertain interference in the system and improve the guidance accuracy, the variable gain extended state observer (TVGESO) is used to estimate the interference in the model, on this basis, the forward interception guidance law is designed based on interference estimation and adaptive fast dynamic surface sliding mode control method. Finally, the simulation results verify that the proposed forward tracking guidance law based on the adaptive fast dynamic surface sliding mode can intercept the target in front of the target and has better guidance accuracy.
