摘要：
Regarding the terminal guidance with accelerated speed, impact point and impact angle constraints, an multiple-constraint super-twisting guidance law for guided projectiles is proposed. First, to simplify the design process, the relative motion model of the missile and the target is converted into a standard second-order form. By applying the Super-Twisting (ST) algorithm, the guidance system can realize convergence faster. By replacing the sign function with saturation function, vibration is decreased. Moreover, an auxiliary guidance scheme is designed by adopting the auxiliary system (AS) theory to solve the problem of accelerated speed constraints. The simulation results indicate that suggested super-twisting sliding-mode guidance law is highly precise and can realize anti-windup control. © 2023 China Ordnance Society. All rights reserved.
