基于混合遗传算法的火箭姿态控制设计方法

针对火箭控制系统姿态网络设计,提出了一种采用遗传算法和模拟退火算法混合的算法进行姿态网络自动设计的方法。该算法实现了已知校正网络幅频特性曲线的幅频向量,通过系统辨识和寻优搜索,可以计算出该网络的传递函数。本文对该算法进行了试验验证,证明该方法可行并优于单纯的模拟退火算法和遗传算法。

The Design Method for Launch Vehicle Attitude Control System Based on Mixed Genetic Algorithms

This paper introduces a design method of launch vehicle attitude control system that can automatically design attitude control network based on a kind of mix optimization algorithm which has mixed genetic algorithm and simulated annealing.The algorithm can calculate the parameters of transfer function through system identification parameter and optimization search if the parameters of magnitude and phase of network curve is known.The mixed optimization algorithm is adopted to solve system identification problem,and the simulation results indicate that it has stronger association ability than that of the other two algorithms,besides faster convergence speed.
