What is control technology and how does it differ from control engineering?
Control technology refers to the technical field that deals with the control and monitoring of machines, systems and processes. It comprises the development, implementation and optimization of control systems that are used to achieve desired states or behaviors in a system.
Control engineering, on the other hand, refers to the branch of control technology that deals with the continuous and automatic adaptation of systems to specific setpoints or reference values. Control systems are used to minimize undesirable deviations from set values and to ensure the stable, precise and efficient functioning of a system.
Essentially, it can be said that control engineering is the general discipline that deals with the monitoring and instruction of systems, while control engineering is a more specific field that deals with the automatic control and regulation of systems.
