For industrial Perspective
Closed-loop and open-loop control systems are two common types of control systems used in industrial applications. While closed-loop control is generally preferred, it may not always be better than open-loop control in all situations.
Closed-loop control, also known as feedback control, continuously measures the output of a system and adjusts the input based on the measured output to achieve a desired result. This type of control is generally more reliable and accurate because it takes into account the system's response to the input and makes adjustments accordingly. Closed-loop control systems can often provide better performance, stability, and accuracy compared to open-loop control systems.
On the other hand, open-loop control, also known as feedforward control, uses a predetermined set of input signals to achieve a desired output. This type of control does not rely on feedback from the system, and thus it may not be as accurate or reliable as closed-loop control. However, open-loop control systems can be simpler and less expensive to implement than closed-loop control systems, and they may be more suitable for certain applications where feedback control is not necessary or practical.
In conclusion, while closed-loop control is generally preferred in industrial applications because of its superior accuracy and reliability, there may be situations where open-loop control is more suitable due to its simplicity and cost-effectiveness. The choice of which control system to use ultimately depends on the specific requirements and constraints of the application at hand
