A 引言通常的现代控制理论不能足以处理有关大系统的问题,从而促进了分散控制的研究。现代控制理论中的一个关键的概念就是状态反馈。通过诸如线性二次品质(LQ)最优控制或极点配置等技术,我们可以利用状态反馈来实现系统行为的改善。然而在系统中实现全状态反馈的要求常常是不可能的,因此已经发展了许多技术来克服这一困难,诸如线性——二次品质——高斯型(LQG)控制、基于观测器的控制以及时域的补
A Introduction The usual theory of modern control can not adequately deal with problems related to large systems, thus facilitating decentralized control. A key concept in modern control theory is state feedback. Using technologies such as linear quadratic quality (LQ) optimal control or pole placement, we can use state feedback to improve system behavior. However, it is often not possible to achieve full state feedback in the system, so many techniques have been developed to overcome this difficulty, such as linear-quadratic quality-Gaussian (LQG) control, observer-based control Time domain complement
