In the present paper, the problem of finite time convergent guidance law design is investigated and a novel guidance scheme with finite time convergence is presented. To improve robustness of the guidance system against highly maneuvering targets, two robust nonlinear techniques are mixed, integral sliding mode and finite time backstepping control. The control loop dynamics are considered as a first order transfer function due to their significant contribution to the guidance loop stability. Furthermore, this guidance law makes the line-of-sight (LOS) angular rate converge to zero in a finite time, before final time of intercepting process. The proposed law is compared to terminal sliding mode guidance law and its superior performance is shown through simulation.
