A methodology for improving tracking precision in servo systems: The equivalent-input-disturbance approach
In mechatronic systems, various interferences, nonlinearities, and characteristic variations exist. To suppress their impact on system control performance and achieve high system performance, we propose the concept of equivalent input disturbance (EID), which equates these performance-influencing factors to a disturbance at the control input end. Furthermore, a servo system structure is proposed for active compensation of this disturbance, enabling the attainment of high precision and performance that cannot be achieved by traditional mechatronic control systems. This report systematically introduces the design and verification results of control systems based on the EID method through practical examples.

报告摘要：机电系统中存在着各种干扰、非线性和特性的变化。为了抑制其对系统控制性能的影响实现系统的高性能，我们提出了等价输入干扰这个概念，把这些对系统性能产生影响的因素等价为一个控制输入端的扰动。并提出了一种伺服系统结构对其进行能动补偿，获得了传统的机电控制系统无法获得的高精度和高性能。本报告通过实例系统地介绍基于等价输入干扰方法的控制系统设计和验证结果。
