Which of the following is a common type of control system used in industrial processes?

The selection of open-loop and closed-loop systems as a common type of control system used in industrial processes is accurate because these two classifications are foundational to how control is implemented in various applications.

Open-loop systems operate without feedback. They rely on predetermined input signals and process parameters to execute operations. This is ideal in situations where the process does not require adjustments based on the output or where the relationship between input and output is straightforward and predictable. For example, a simple timed irrigation system would turn on and off based on a set schedule without measuring the soil moisture.

Closed-loop systems, on the other hand, incorporate feedback to continuously monitor the output of a process and adjust the inputs accordingly to maintain the desired level of performance. This is critical in processes where maintaining specific conditions is essential, such as temperature control in a furnace or pressure regulation in a pipeline. By using sensors to monitor the output and controllers to adjust inputs, closed-loop systems can correct any deviations from the target conditions, leading to improved efficiency and reliability.

While manual controls, exclusive analog systems, and only mechanical systems may have their specific applications, they don’t encompass the broad range of capabilities and modern technological integration found in open-loop and closed-loop control systems. In contemporary industrial processes, a combination of these
