9985739 sarangapani电信系统、无线网络、制造业和其他领域的新发展对先进的离散时间自适应控制器的设计提出了严格的要求。因此，控制器技术的离散时间版本很重要，因为所有的控制器实现都是在数字计算机上进行的。此外，由于传感器、硬件的快速发展，更重要的是由于环境问题对这些系统施加的法规，包括工业、国防部在内的复杂非线性系统的性能要求变得越来越严格。其结果是一个复杂的大规模分布式现代系统。自适应和神经网络（AN）控制工具和传感器技术有望在不确定性、振动抑制、精确运动控制和微物体操纵、微传感器开发、死区补偿、诊断/预测等方面改善学习。该项目的目标是提供下一代控制器，该控制器应能够与各种传感器接口，允许重新配置和快速原型功能，具有保证的性能，并由严格且可重复的设计和数学框架支持，包括：开发和实现用于机器级操作的高级实时反馈控制器。基于微传感器的MEMS器件和系统组装/控制的开发与实现。用于诊断/预后应用的基于传感器的自适应控制器的开发和实现。通信网络实时自适应控制器的开发与实现[j]

9985739SarangapaniNew developments in telecommunication systems, wireless networks, manufacturing, and elsewhere place severe demands on the design of advanced discrete-time adaptive controllers. Therefore, discrete-time version of controller techniques is of importance since all the controller implementations are carried out on a digital computer. Further, the performance requirements for complex nonlinear systems including industrial, DoD are becoming more stringent due to rapid advances in sensors, hardware, and more importantly the regulations imposed on these systems due to environmental concerns. The result is a complex large-scale distributed modern day system. Adaptive and neural network (AN) control tools and sensor technologies hold out promise of improved learning under uncertainty, vibration suppression, precise motion control and micro object manipulation, microsensor development, deadzone compensation, diagnostics/prognostics and more.The goal of this project is to provide a next generation controller, which should be able to interface to a wide variety of sensors, allowing reconfiguration and rapid prototyping capabilities, has guaranteed performance, and is supported by a rigorous and repeatable design and mathematical framework, to include: Development and Implementation of Advanced Real-Time Feedback Controllers for Machine Level Operations.Development and Implementation of Microsensor-based Assembly/Control of MEMS devices and Systems. Development and Implementation of Sensor-based Adaptive Controllers for Diagnostic/Prognostic Applications.Development and Implementation of Real-Time Adaptive Controllers for Communication Networks.***
