Reset Control for High-Performance Electro-Mechanical Devices

本研究项目的目标是开发一种新的设计技术，该技术结合了一类复位控制器，其中Clegg积分器是一个典型的例子。这是通过利用这种独特非线性的特定复位特性来实现的。初步研究已经得到了低阶复位系统的严密稳定性条件，并为提出重要的稳定性猜想提供了见解。除了研究这一猜想外，还将解决使用积分二次约束（iqc）的性能和稳定性问题，并在多模态切换系统框架内开发新的重置规则。这种复位控制器的几个工业实现已经存在，其中大量的模拟和实验用于验证稳定的操作。拟议研究的影响将有助于减轻对此类测试的需求，这是工业中有限使用复位控制器的主要因素。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发现巨大的商业利益，特别是在数据存储外设方面。

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.
