Design of Control Systems
INTRODUCTION
All the foundations of analysis that we have laid in the preceding chapters led to the preceding chapters led to the ultimate goal of design of control systems. Starting with the controlled process such as that shown by the block diagram in Fig.1,control system design involves the following three steps:
1. Determine what the system should do and how to do it (design specifications).
2. Determine the controlled or compensator configuration, relative to how it is connected to the controlled process.
3. Determine the parameter values of the controller to achieve the design goals.
These design tasks are explored further in the following sections.

引言
我们在前面几章中介绍了许多分析控制系统的方法，其最终目的就是为了能够设计控制系统。设计像方框图1所示的控制系统一般包括以下三步：
确定系统应该做什么以及应该怎么做（设计要求）。
根据控制器或校正器在受控过程中的连接方式，确定其结构配置。
确定控制器的参数使得系统达到设计目标。
我们将在下面详细介绍控制系统的设计问题。
设计要求
设计要求一般用来描述应该做什么以及应该怎样做。根
