控制工程（英语：Control engineering）是有关控制理论研究与应用的一门工程学。控制系统的实现通常基于传感器的使用，它可以测量被控制设备的性能参数，然后收集到的数据以反馈的形式施加到执行器上，使得执行器输出一定的信号，确保系统工作在预期的状态。工程师可以设计无需人介入、可以自适应、自动修正误差的设备系统，这种系统被称为“自动控制”，例如汽车的巡航定速系统。控制工程在本质上是一个交叉学科，而描述系统行为的数学模型则又是重中之重。

Control engineering or control systems engineering is the engineering discipline that applies control theory to design systems with desired behaviors. The practice uses sensors to measure the output performance of the device being controlled and those measurements can be used to give feedback to the input actuators that can make corrections toward desired performance. When a device is designed to perform without the need of human inputs for correction it is called automatic control (such as cruise control for regulating the speed of a car). Multi-disciplinary in nature, control systems engineering activities focus on implementation of control systems mainly derived by mathematical modeling of systems of a diverse range.
