The term disturbance variable compensation originates from the fields of automation, industry and Industry 4.0, as well as the Internet of Things. In these fields, the aim is to control machines and processes as efficiently and accurately as possible.
Disturbances are influences that can disrupt a production process. These can be, for example, temperature fluctuations, vibrations or other external influences that result in a product not being manufactured as desired.
Disturbance compensation is a method used to balance out such disruptions. Sensors continuously measure the current values, and intelligent systems adjust the control of the machines so that the end result is still correct.
For example: In a factory, a robot produces car parts. Suddenly, the room temperature fluctuates significantly, which can affect the dimensions of the parts. With disturbance compensation, the control system detects the temperature fluctuation and reacts immediately by slightly adjusting the robot's movements. This ensures that the car parts always remain within the desired dimensions – despite external disturbances.
Disturbance variable compensation thus helps to secure production quality and reliability and is therefore an important component of modern manufacturing processes.
