integration

积分

PID控制器就是根据偏差,利用比例(proportional)、积分(integration)、微分(differentiation)计算出控制量进行控制的. PID控制器问世至今已有近几十年的历史,它以其结构简单、稳定性好、工作可靠、调整方便而成为工业控制的主要技术之一.

time invariant

时不变

比如,线性系统的最重要性质,叠加性(superposition)就可以通过微分方程很容易得出;时不变(time invariant)性质也是一样. 很有物理意义的规律在数学中不过是一种变形或者变换或者简单的运算. 数学形式和物理意义的赋予之间的矛盾是必须抓牢的.
