说明：  在日常生活中，所谓自适应是指生物能改变自己的习性以适应新的环境的一种特征。因此，直观地说，自适应控制器应当是这样一种控制器，它能修正自己的特性以适应对象和扰动的动态特性的变化。
(In everyday life, self-adaptation is a characteristic of organisms that can change their habits to adapt to new environments. Therefore, intuitively speaking, the adaptive controller should be such a kind of controller, it can modify its own characteristics to adapt to the changes of the dynamic characteristics of the object and disturbance.)
