Abstract:

As an important defensive weapon, the rudder system of the ship-borne decoy jamming missile plays a central role in ensuring the dynamic quality and flight safety of the flight control system. Traditional PID control algorithms have limitations in terms of anti-interference and fast response capabilities. Therefore, the particle swarm optimization technology is introduced and the advantages of self-disturbance rejection and intelligent algorithms are integrated to improve the self-disturbance rejection control algorithm and enhance the anti-interference capability and stability of the rudder system. In view of the offline adjustment problem of self-disturbance rejection control, the use of particle swarm intelligence algorithm to optimize the parameters of the rudder system controller online is proposed to adapt to environmental changes and adjust in time, solving the problem of limited control performance. The simulation results of the system show that compared with traditional PID algorithm and ADRC algorithm, the self-disturbance rejection control method based on particle swarm optimization has better performance in the position loop control of the rudder system.
