摘要：
In the terminal guidance section of naval gun networked guided projectiles while striking near shore maneuver target, a finite time distributed fuzzy cooperative guidance law was proposed with impact angle constraint. The relative motion model of networked projectiles and target was constructed, and extended state observer (ESO) was designed to estimate target acceleration at tangent and normal of velocity. Aiming at guaranteeing the consensus of impact times in finite time, integral sliding mode was adopted to designed distributed finite time cooperative guidance law in the line-ofsight (LOS). In vertical LOS, in order to zeroing the error and angular of LOS angle in finite time, as well as improving terminal divergence phenomenon of control instruction, a two stage guidance law was designed by nonsingular terminal sliding mode. And fuzzy adaptive approximator was applied to weaken the chattering of control instruction and compensate interference. The states of whole system are all uniformly bounded and finite time convergence, which is proved by Lyapunov theory. Simulation experiment shows this guidance law makes networked projectiles possess well guidance performance while striking targets with different acceleration forms. © 2020, Editorial Department of Control Theory & Applications South China University of Technology.
