标题： An approach to the LQG/LTR design problem with specifications for finite-dimensional SISO control systems

摘要： 这是一篇说明性论文，讨论了针对有限维单输入单输出控制系统中的LQG/LTR设计问题的一种方法。 该方法基于权重增强的利用，以将设计规范纳入LQG补偿器设计的LTR技术框架中。 LQG补偿器旨在同时满足以期望的灵敏度和控制器噪声灵敏度函数表示的给定分析低频和高频设计规范。 本文面向非专业读者，特别是对有限维LQG理论感兴趣，并希望在现实情况下设计反馈补偿器以实现闭环性能和鲁棒性调整的实践者。 所提出的方法通过一个详细的数值示例进行说明：具有弹性安装转子的电流控制直流电机的扭矩控制。 显示英文摘要

摘要： This is an expository paper which discusses an approach to the LQG/LTR design problem for finite-dimensional SISO control systems. The approach is based on the utilisation of weighting augmentation for incorporating design specifications into the framework of the LTR technique for LQG compensator design. The LQG compensator is to simultaneously meet given analytical low- and high-frequency design specifications expressed in terms of desirable sensitivity and controller noise sensitivity functions. The paper is aimed at nonspecialists and, in particular, practitioners in finite-dimensional LQG theory interested in the design of feedback compensators for closed-loop performance and robustness shaping of SISO control systems in realistic situations. The proposed approach is illustrated by a detailed numerical example: the torque control of a current-controlled DC motor with an elastically mounted rotor.
