ABSTRACT

Firstly, aiming at the simplified linear model of aircraft pitch channel, a basic framework of angle-of-attack stabilization controller considering limiting amplitude is designed. Particle swarm optimization (PSO) algorithm is introduced to adjust the parameters of the aircraft in terms of the ratio, angular velocity feedback parameters and integral parameters. Finally, the digital simulation is carried out and good results are obtained. It shows that the particle swarm optimization algorithm can automatically select the parameters of the aircraft, thus solving the problem of waste of manpower and material resources by manual parameter adjustment relying on experience.
