Reset Control for High-Performance Electro-Mechanical Devices

这个研究项目的目标是开发一种新的设计技术，它包含一类复位控制器，其中克莱格积分器是一个很好的例子。这是通过利用这种独特的非线性的特定复位性质来实现的。初步的研究已经产生了严格的稳定性条件，低阶复位系统，并提供了一个重要的稳定性猜想的见解。除了研究这个猜想，性能和稳定性问题，使用积分二次约束（IQCs）将得到解决，并将开发新的重置规则的框架内的多模态切换系统。 已经存在这种复位控制器的几种工业实现，其中广泛的模拟和实验用于验证稳定操作。拟议研究的影响将有助于减轻这种测试的需要，这是工业中复位控制器使用有限的主要因素。在高性能数字伺服系统中成功开发和演示复位控制器可能会引起巨大的商业兴趣，特别是在数据存储外围设备中。

The goal of this research project is to develop a new design technique that incorporates a class of reset controllers of which the Clegg integrator is a prime example. This is accomplished by exploiting the specific reset nature of this unique nonlinearity. Initial research has yielded tight stability conditions for low-order reset systems and provides insight to pose an important stability conjecture. Besides studying this conjecture, performance and stability issues using integral quadratic constraints (IQCs) will be addressed and new reset rules within the framework of multi-modal switched systems will be developed. Several industrial implementations of such reset controllers, where extensive simulations and experiments were used to verify stable operations, already exist. The impact of the proposed research will help to alleviate the need for such testing which is the main factor for the limited use of reset controllers in industry. Successful development and demonstration of reset controllers in high performance digital servo systems is likely to find great commercial interest, especially in data-storage peripherals.
