Abstract

This study presents a shaped reset feedback control strategy to enhance the performance of precision motion systems. The approach utilizes a phase-lead compensator as a shaping filter to tune the phase of reset instants, thereby shaping the nonlinearity in the first-order reset control. The design achieves either an increased phase margin while maintaining gain properties or improved gain without sacrificing phase margin, compared to reset control without the shaping filter. Then, frequency-domain design procedures are provided for both Clegg Integrator (CI)-based and First-Order Reset Element (FORE)-based reset control systems. Finally, the effectiveness of the proposed strategy is demonstrated through two experimental case studies on a precision motion stage. In the first case, the shaped reset control leverages phase-lead benefits to achieve zero overshoot in the transient response. In the second case, the shaped reset control strategy enhances the gain advantages of the previous reset element, resulting in improved steady-state performance, including better tracking precision and disturbance rejection, while reducing overshoot for an improved transient response.

加强复位控制相位与引线整形滤波器：应用于精密运动系统

提出了一种形状复位反馈控制策略，以提高精密运动系统的性能。该方法利用超前相位补偿器作为整形滤波器来调整复位瞬间的相位，从而对一阶复位控制中的非线性进行整形。与没有整形滤波器的复位控制相比，该设计既可以在保持增益特性的同时增加相位裕度，也可以在不牺牲相位裕度的情况下提高增益。然后，给出了基于Clegg积分器（CI）和基于一阶复位元件（FORE）的复位控制系统的频域设计步骤。最后，通过两个精密运动平台的实验案例，验证了所提策略的有效性。在第一种情况下，形状复位控制利用相引优势在瞬态响应中实现零超调。在第二种情况下，形状复位控制策略增强了先前复位元件的增益优势，从而提高了稳态性能，包括更好的跟踪精度和抗干扰性，同时减少了超调量，从而改善了瞬态响应。

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
