Research on control method of anti-aircraft correction ammunition based on particle swarm optimization

In order to improve the ability of anti-aircraft trajectory correction ammunition to intercept maneuvering targets, a control method of missile-borne actuator was proposed. The particle trajectory model was established. According to the basic principle of trajectory correction, the optimal model of impulsive control was obtained. The ignition pulse control strategy was given according to the characteristics of impulse control. The particle swarm optimization (PSO) was applied to optimizing the impulsive control instructions. By introducing the minimum consumption principle of pulse energy, the fitness function was improved. The overall optimal solutions of control instructions were searched. Simulation results show that this control method can make anti-aircraft ammunition gain high hit-precision to intercept maneuvering target.
