| 摘 要： | 本文从如何解决系统输出精确跟踪给定值这一控制问题出发，基于过程模型逆的思想，对解决这一问题的反馈控制方法进行了讨论。首先介绍了这一控制问题的概念性解以及其难以物理实现的原因。接着，讨论了利用高增益反馈回路构造近似的过程模型逆的方法，以及其实现条件。最后，分析了反馈控制增益选择需要综合考虑各种利弊因素的权衡思想。整个讨论过程中通过一些仿真例子来加以验证。

| Abstract: | The feedback control method, which solves the control problem that the system output precisely tracks the reference, is discussed on the basis of the process inverse. We first introduce a conceptual solution to the control problem via inversion, and analyze the causes that this solution is not carried out in practice. We then study the method that generates an approximate inverse of processes by using a highgain feedback loop. Finally, trade-offs in choosing feedback gain are discussed between completing issues. Some simulation examples are given to illustrate the results. |
