Sliding-mode variable structure finite-time convergence guidance law
摘要
Abstract
Based on the sliding-mode variable structure control, a finite-time convergent sliding-mode guidance law is presented for the guidance systems with terminal incident angle constraint. This guidance law ensures the angular rate of the line-of-sight (LOS) to converge to zero rapidly, while the missile angular converges to the desired incident angle. By employing the finite-time stability theory of nonlinear control systems to analyze the guidance law, we obtain the mathematical expression of the convergence time, thus confirming the finite-time convergence of the guidance system. Simulation results show that the guidance law is effective and robust.关键词
