摘　　要：针对倾转翼飞机过渡段模式飞行时,其动力学特性呈现出的强非线性和强耦合的特点,传统的PID控制方法难以设计其控制参数并实现定高控制。本文将遗传算法和PID控制理论相结合,基于遗传算法整定获得全局最优的PID控制参数以保证良好的定高控制效果。仿真试验结果表明,经遗传算法整定参数后的PID控制能够更好地实现对倾转翼飞机过渡段的定高飞行控制。Aiming at the characteristics of strong non-linearity and strong coupling of the dynamic characteristics of the tilting wing aircraft during the transition mode flight,the traditional PID control method is difficult to design its control parameters and achieve fixed height control.In this paper,genetic algorithm and PID control theory are combined,and the global optimal PID control parameters are obtained based on the genetic algorithm tuning to ensure a good fixed height control effect.The simulation test results show that the PID control parameters are obtained by the genetic algorithm tuning can better achieve the fixed-height flight control of the tilting wing aircraft transition section.
