[[Control engineering]] focuses on the [[Mathematical model|modeling]] of a diverse range of [[dynamic system]]s and the design of [[Controller (control theory)|controller]]s that will cause these systems to behave in the desired manner.{{sfn|Bissell|1996|p=17}} To implement such controllers, electronics control engineers may use [[electronic circuit]]s, [[digital signal processor]]s, [[microcontroller]]s, and [[programmable logic controller]]s (PLCs). [[Control engineering]] has a wide range of applications from the flight and propulsion systems of [[commercial airliner]]s to the [[cruise control]] present in many modern [[automobile]]s.{{sfn|McDavid|Echaore-McDavid|2009|p=95}} It also plays an important role in [[industrial automation]].

Control engineers often use [[feedback]] when designing [[control system]]s. For example, in an [[automobile]] with [[cruise control]] the vehicle's [[speed]] is continuously monitored and fed back to the system which adjusts the [[Internal combustion engine|motor's]] [[Power (physics)|power]] output accordingly.{{sfn | Åström | Murray | 2021 | p=108}} Where there is regular feedback, [[control theory]] can be used to determine how the system responds to such feedback.

Control engineers also work in [[robotics]] to design autonomous systems using control algorithms which interpret sensory feedback to control actuators that move robots such as [[autonomous vehicle]]s, autonomous drones and others used in a variety of industries.{{sfn|Fairman|1998|p=119}}
