摘    要:针对一种翼展为550mm的电动力微型无人机的优化设计问题.对粒子群优化算法进行了改进,弥补了原来算法当最优解在设计变量上下限边界时无法找到最优解的缺陷,然后对电动力无人机的电池容量的优化选取进行了探讨,最后对该机进行了研制和试飞。由试飞结果可知,该机的留空时间为68min,与优化计算结果十分相近,证明了优化计算结果的可行性和高精度。

关 键 词:粒子群优化算法  遗传算法  变复杂度的优化计算方法  微型无人机

Abstract:An improvement was made over the basic particle swarm optimization algorithm (PSO) in this paper to solve the optimization problem of a micro air-vehicle with a wing span of 550 mm. The results of optimization showed that the improvement was successful. Then the relationship between the volume of the battery and the performance of electrical powered aircraft was discussed. We also built and tested the mini-UAV. This plane achieved an endurance of 68 minutes and the results of test flights proved the effectiveness and high accuracy of the optimization.
Keywords:particle swarm optimization algorithm  genetic algorithm  variable fidelity optimization technique  micro air vehicle
