非接触式、磁悬浮、大规模驱动的可变形反射镜及其控制系统的成功设计需要使用中高保真度的混合多学科仿真模型，包括：可变形结构、反射镜与其参考背板之间的气膜流体动力学、传感器和致动器动力学、控制系统。这些模型必须满足分析、设计和验证完全分散控制解决方案的各种需求，并模拟所有现场操作阶段，包括初始反馈设计、静态前馈矩阵的识别和控制自调谐。本文介绍了相关的建模技术，以及验证所提出的能力的各个方面的一些结果和实验相关性。
The successful design of non contact, magnetically levitated, massively actuated deformable mirrors and their control system requires the use of medium to high fidelity hybrid multidisciplinary simulation models, encompassing: deformable structures, fluid dynamics of the air film interposed between the mirror and its reference backplane, sensor and actuator dynamics, the control system. Such models must serve the diverse needs for the analysis, design and verification of a fully decentralized control solution and to simulate all of on the field operational phases including initial feedback design, the identification of the static feed-forward matrix and control self tuning. The paper presents the related modeling techniques along with a few results and experimental correlations validating various aspects of the presented capabilities.
