Control theory is a field of control engineering and applied mathematics that deals with the control of dynamical systems in engineered processes and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, while minimizing any delay, overshoot, or steady-state error and ensuring a level of control stability; often with the aim to achieve a degree of optimality.
Centrifugal governor in a Boulton & Watt engine of 1788
An electromechanical timer, normally used for open-loop control based purely on a timing sequence, with no feedback from the process
Example of a single industrial control loop; showing continuously modulated control of process flow.
Control engineering or control systems engineering is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments. The discipline of controls overlaps and is usually taught along with electrical engineering, chemical engineering and mechanical engineering at many institutions around the world.
Control systems play a critical role in space flight.
Control of fractionating columns is one of the more challenging applications.
The centrifugal governor is an early proportional control mechanism.
