Abstract

In this paper, a satellite with two flexible appendages and a central hub is considered. The piezoelectric layers are attached to both side of the appendages and used as actuators. The governing equations of motion are derived based on Lagrange method. Using Rayleigh-Ritz technique ordinary differential equations of motion are obtained. A robust inverse dynamic control is applied to the system to not only control the three axes manoeuvre of the satellite but also suppress the vibrations of the flexible appendages. Finally, the system is simulated and simulation results show good performance of this controller.

具有压电层的机动智能柔性卫星的鲁棒逆动力学控制

本文考虑了一颗具有两个柔性附件和一个中心枢纽的卫星。压电层连接到附件的两侧并用作致动器。基于拉格朗日方法导出了运动的控制方程。利用瑞利-里兹技术得到了运动的常微分方程。将鲁棒逆动力学控制应用于该系统，不仅控制了卫星的三轴操纵，而且抑制了柔性附件的振动。最后对系统进行了仿真，仿真结果表明该控制器具有良好的性能。

期刊介绍： The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world. Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email. IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out. Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model. In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay. The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
