PROJECT TITLE :

Finite time sliding sector guidance law with acceleration saturation constraint

ABSTRACT:

A unique steerage law utilising variable structure management with finite time sliding sector is proposed. In contrast with the normally used notion of asymptotic stability in typical sliding sector, a finite time sliding sector is outlined as a subset of state house in that the Lyapunov function candidate satisfies the finite time stability condition. For the steerage system, the analytical solution of a state-dependent differential Riccati equation is achieved to see the finite time sliding sector. Then, based mostly on the finite time sliding sector, a sliding sector guidance law is designed by considering the target acceleration as a bounded uncertainty. Furthermore, the finite time sliding sector steerage law is even extended to the case where missile acceleration saturation constraint is taken into account. Simulation results show that the new guidance law is highly effective.
