针对火星探测器飞行距离遥远和飞行环境复杂带来总体设计参数难以优化的问题,建立以遥感性能和总重为综合优化目标的优化模型,考虑探测器的轨道、载荷、电源等分学科,基于协同优化方法建立火星探测器的系统级和学科级优化函数,采用自适应动态罚函数加快优化的收敛速度,最终获得协同一致的优化结果。仿真结果表明: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。
Aimed at the problem that the overall design parameters are difficult to optimize due to the flying distance of the Mars rover and the complicated flight environment, an optimization model based on the remote sensing performance and the total weight for the overall optimization objective is established. Considering the sub-disciplines such as the orbit, the load and the power of the detector, The synergetic optimization method is used to establish the system-level and discipline-level optimization functions of the Mars rover. The adaptive dynamic penalty function is used to speed up the convergence of the optimization and finally the synergetic optimization results are achieved. The simulation results show that the synergetic optimization method is applicable to the optimization and optimization of the overall parameters of the Mars probe. It can provide technical reference for the overall design of the detector.
