A 3D Variable Structure Guidance Law for Missiles in Attacking Maneuvering Targets

When the missile attacks the maneuvering targets using the variable structure guidance lawchattering of line-of-sight angular rate may happen.A 3-dimensional variable structure guidance law was presented based on RBF neural network adaptive parameter adjustment which combining the self-learning ability of RBF neural network with the variable structure control theory.It solves the problem of the variable structure that the parameter of it is not easy to be determined.So it can reduce the chattering and improve the missile's attack accuracy.The simulation results show that the new guidance law has strong adaptability and robustnesswhich can meet the need of guidance.
