Adaptive Secure Missile Guidance Against Additive and Multiplicative Cyber-Attacks

In this paper, a novel secure guidance law is proposed to address additive and multiplicative cyber-attacks injected into guidance commands. From an engineering perspective, the two kinds of cyber-attack are assumed to be bounded. Then, directed by Lyapunov theory, their bounds are estimated by designing adaptive laws. Meanwhile, the convergence of line-of-sight rates and angle errors is guaranteed, which helps to intercept the maneuvering target successfully with terminal angle constraints. Finally, numerical simulations show the effectiveness of the proposed scheme.
