摘要

由于对性能的要求越来越严格,预计下一代可变形反射镜将表现出低频柔性动态特性,并包含大量空间分布式致动器。面对日益复杂的系统特性,有必要识别柔性动态行为,以便进行设计验证和下一代控制。本文旨在开发一种统一的方法,用于识别具有大量空间分布式致动器和有限数量传感器的机械系统。本文采用局部建模技术,开发了一种基于频域的方法。模态建模框架用于分析设计并创建未测量的输出。所提出的方法被应用于一个实验性可变形镜子案例研究,以说明所提出方法的有效性。

Identification of an overactuated deformable mirror system with unmeasured outputs

Next-generation deformable mirrors are envisaged to exhibit low-frequency flexible dynamics and to contain a large number of spatially distributed actuators due to increasingly stringent performance requirements. The increasingly complex system characteristics necessitate identifying the flexible dynamic behavior for design validation and next-generation control. The aim of this paper is to develop a unified approach for the identification of mechanical systems with a large number of spatially distributed actuators and a limited number of sensors. A frequency domain-based approach using local modeling techniques is developed. The modal modeling framework is employed to analyze the design and create outputs that were not measured. The proposed approach is applied to an experimental deformable mirror case study that illustrates the effectiveness of the proposed approach.

期刊介绍: Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes. It relates to the design of systems, devices and products aimed at achieving an optimal balance between basic mechanical structure and its overall control. The purpose of this journal is to provide rapid publication of topical papers featuring practical developments in mechatronics. It will cover a wide range of application areas including consumer product design, instrumentation, manufacturing methods, computer integration and process and device control, and will attract a readership from across the industrial and academic research spectrum. Particular importance will be attached to aspects of innovation in mechatronics design philosophy which illustrate the benefits obtainable by an a priori integration of functionality with embedded microprocessor control. A major item will be the design of machines, devices and systems possessing a degree of computer based intelligence. The journal seeks to publish research progress in this field with an emphasis on the applied rather than the theoretical. It will also serve the dual role of bringing greater recognition to this important area of engineering.
