针对火星探测器飞行距离遥远和飞行环境复杂带来的总体设计参数难以优化的问题,建立以对火星分辨率和覆盖率综合为优化目标的优化问题,对与总体目标相关的参数进行分析建模,考虑到优化目标与探测器的多个分系统相关,直接求解存在参数耦合难以协调的问题,基于动态罚函数的协同优化方法将优化问题进行分解,从而将一个复杂优化问题转化为多个子问题的并行协同优化问题。再采用多方法协作优化算法对问题进行求解,获得协同一致的优化结果,从而验证了协同优化方法应用于火星探测器总体参数优化的可行性和有效性,可为探测器的总体设计提供技术参考。
In view of the problem that the overall design parameters brought by the flying distance of the Mars rover and the complicated flight environment are difficult to be optimized, an optimization problem that optimizes the Mars resolution and coverage is established. The parameters related to the overall target are analyzed and modeled Considering that the optimization objective is related to many subsystems of the detector, the problem of parameter coupling is difficult to reconcile directly, and the optimization problem based on dynamic penalty function is decomposed to transform a complex optimization problem into several sub-problems Parallel Collaborative Optimization. Then, the multi-method collaborative optimization algorithm is used to solve the problem, and the synergetic optimization results are obtained. This verifies the feasibility and effectiveness of the collaborative optimization method in the optimization of the overall parameters of the Mars rover, which can provide technical reference for the overall design of the rover .
