US-Egypt Cooperative Research: Design, Fabrication, and Intelligent Control of Nanopositioning Devices

描述：该奖项旨在支持伊利诺斯州芝加哥伊利诺斯大学机械工程系Sabri Cetinkunt博士和埃及开罗艾因沙姆斯大学设计与生产工程系Magdy Abdelhameed博士之间的合作项目。目标是开发用于高精度加工的纳米定位机构（压电刀架）的新控制系统，特别是在加工脆性材料（如镜子，硅片和陶瓷）时。控制纳米定位器运动的控制系统的性能对保持稳定、准确的轨迹跟踪至关重要。这些研究人员将开发基于神经网络架构的新控制算法。具体来说，他们将使用小脑模型关节控制器（CMAC）神经网络架构来改善动态控制性能。他们还将在艾因沙姆斯大学的实验室设计和实施机电一体化控制系统的硬件设置。这将包括一个纳米定位机构，传感系统，PZT致动器的功率放大器和实时控制器。项目范围：该项目支持两名有经验的研究者之间的合作。伊利诺伊大学芝加哥分校的实验室有必要的设备。他有使用基于神经网络的控制器进行纳米加工和快速刀具后加工操作的经验。埃及合作者在制造系统的动态和控制方面有一个活跃的研究项目，在机电一体化方面也有一个活跃的研究项目。该项目将包括两所大学之间的研究生交流。该提案符合INT在共同感兴趣的领域支持合作研究的目标。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0111263CetinkuntDescription: This award is to support a collaborative project between Dr. Sabri Cetinkunt, Department of Mechanical Engineering, University of Illinois at Chicago, Chicago, Illinois and Dr. Magdy Abdelhameed, Design and Production Engineering Department, Ain Shams University, Cairo, Egypt. The goal is to develop new control systems for a nano-positioner mechanism (piezoelectric tool post) used in high precision machining, specially when machining brittle materials such as mirrors, silicon wafers and ceramics. The performance of control systems used in controlling the motion of a nano-positioner is crucial in maintaining a stable and accurate trajectory tracking. These investigators will develop new control algorithms based on neural network architectures. Specifically they will use Cerebellar Model Articulation Controller (CMAC) neural network architecture to improve the dynamic control performance. They will also design and implement a hardware setup for the mechatronics control system at the laboratory at Ain Shams University. This will include a Nano-positioner mechanism, sensing system, power amplifier of the PZT actuator and the real time controller.Scope: The project supports collaboration between two experienced investigators. The laboratory at the University of Illinois at Chicago has the required facilities. Dr. Cetinkunt has experience using neural net-based controllers for nanomachining and fast tool post machining operations. The Egyptian collaborator has an active research program in the dynamic and control of manufacturing systems, and an active research program in mechatronics. The project will include exchange of graduate students between the two universities. The proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
