控制系统意味着通过它可以按照所希望的方式保持和改变机器、机构或其他设备内任何感兴趣或可变的量。控制系统同时是为了使被控制对象达到预定的理想状态而实施的。控制系统使被控制对象趋于某种需要的稳定状态。 例如，假设有一个汽车的驱动系统，汽车的速度是其加速器位置的函数。通过控制加速器踏板的压力可以保持所希望的速度（或可以达到所希望的速度变化）。这个汽车驱动系统（加速器、汽化器和发动机车辆）便组成一个控制系统。

Control means that any interesting or variable quantity in a machine, mechanism or other equipment can be maintained and changed in a desired way through it. At the same time, the control system is implemented to make the controlled object reach a predetermined ideal state. The control system makes the controlled object tend to some required stable state.
For example, suppose there is a driving system of a car, and the speed of the car is a function of its accelerator position. The desired speed can be maintained (or the desired speed change can be achieved) by controlling the pressure of the accelerator pedal. This automobile drive system (accelerator, carburetor and engine vehicle) constitutes a control system.
