Abstract

Abstract. The cell-mapping method, due to its global optimality, has been applied to solve multi-objective optimization problems (MOPs) and optimal control problems. However, the curse of dimensionality limits its application in high-dimensional systems. In this paper, the multi-parameter sensitivity analysis is investigated to reduce the parameter space dimension, which broadens the application of cell mapping to MOPs in high-dimensional parameter space. A post-processing algorithm for MOPs is introduced to help choose proper control parameters from the Pareto set. The proposed scheme is applied successfully in the control parameter optimization of an adaptive nonsingular terminal sliding-mode control for an antenna servo system on a disturbed carrier. Moreover, as the existing global optimal tracking control with an adjoining cell-mapping method may generate tracking-phase differences, an optimal-sliding-mode combined-control strategy is proposed. By using the combined-control strategy, the azimuth and pitch angles of the antenna system are controlled to catch up to a target trajectory with the minimum cost function and to keep high-precision tracking after that.

将小区映射应用于干扰载波上天线伺服系统的控制优化

摘要单元映射法因其全局最优性，已被用于解决多目标优化问题（MOPs）和最优控制问题。然而，维数诅咒限制了它在高维系统中的应用。本文研究了多参数灵敏度分析，以降低参数空间维度，从而拓宽了单元映射在高维参数空间中 MOP 的应用。研究还引入了一种澳门威尼斯人官网程后处理算法，以帮助从帕累托集合中选择合适的控制参数。所提出的方案被成功应用于干扰载波上天线伺服系统的自适应非正弦终端滑模控制的控制参数优化。此外，由于现有的全局最优跟踪控制与邻接单元映射方法可能会产生跟踪相位差，因此提出了一种最优滑模组合控制策略。通过使用组合控制策略，控制天线系统的方位角和俯仰角，以最小的成本函数追赶目标轨迹，并在追赶目标轨迹后保持高精度跟踪。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
