研究了应用模型参考的纵向控制增稳系统的优化设计,并应用于某型运输机纵向控制增稳系统的设计中。首先根据飞机纵向等效系统模型给出了参考模型的形式,之后根据一级飞行品质的要求给出了参考模型的参数选取方法和步骤。然后使用粒子群优化算法优化设计了基于模型参考的控制增稳系统。最后提出利用粒子群优化算法的时域等效拟配方法进行等效系统拟配和飞行品质评价。仿真结果表明,设计得到的控制增稳系统可以同时满足时域的、一级飞行品质的和鲁棒性的设计要求,证明了优化设计方法的有效性和高效性。
The optimization design of longitudinal control stabilizing system with reference to the model is studied and applied to the design of longitudinal stabilizing system for a certain transporter. First, the form of the reference model is given according to the longitudinal equivalent system model of the aircraft, and then the method and procedure for parameter selection of the reference model are given according to the requirements of the first-class flight quality. Then particle swarm optimization algorithm is used to optimize the control stabilization system based on model reference. Finally, the time-domain equivalent fitting method using Particle Swarm Optimization (PSO) is proposed to evaluate the equivalent system and the flight quality. The simulation results show that the designed control augmentation system can meet the design requirements of time-domain, first-class flight quality and robustness simultaneously, and prove the effectiveness and efficiency of the optimal design method.
