摘 要： 最优控制理论是现代控制理论的核心，控制理论的发展来源于控制对象
的要求。尽 50 年来，科学技术的迅速发展，对许多被控对象，如宇宙飞船、导
弹、卫星、和现代工业设备的生产过程等的性能提出了更高的要求，在许多情况
下要求系统的某种性能指标为最优。这就要求人们对控制问题都必须从最优控制
的角度去进行研究分析和设计。最优控制理论研究的主要问题是：根据已建立的
被控对象的时域数学模型或频域数学模型，选择一个容许的控制律，使得被控对
象按预定要求运行，并使某一性能指标达到最优值

Abstract： The Optimal Control Theory is the core of the Modern Control
Theory，the development of control theory comes from the requires of the
controlled objects.During the 50 years， the rapid development of the
scientific technology puts more stricter requires forward to mang
controlled objects ， such as the spacecraft ， the guide missile ， the
satellite，the productive process of modern industrial facilities，and
so on，and requests some performance indexes that will be best in mang
cases.To the control problem，it requests people to research ,analyse，
and devise from the point of view of the Optimal Control Theory.
There are mang major problems of the Optimal Control Theory
studying,such as the building the time domain’s model or the frenquency
domain’s model according to the controlled objects,controlling a control
law with admitting, making the controlled objects to work according
to the scheduled requires, and making the performance index to
reseach to a best optimal value.
