What is the main purpose of a closed loop control system?

The main purpose of a closed loop control system is to adjust based on sensor feedback. This type of system continuously monitors the output of a process and compares it to a desired setpoint or target. By receiving real-time data from sensors, the system can make necessary adjustments to the inputs or controls to ensure that the output remains within desired parameters. This feedback loop is crucial for maintaining accuracy and stability in various applications.

For instance, in an automotive context, ABS (Anti-lock Braking System) uses a closed loop control system to monitor wheel speed and adjust brake pressure accordingly to prevent skidding. This dynamic adjustment is essential for optimal performance and safety.

In contrast, the other options do not capture the essence of what closed loop control systems are designed to achieve. Storing data is more related to memory and data management rather than active control. Enhancing target acquisition pertains more to sensors and detection systems rather than the feedback adjustment process. Increasing propulsion efficiency may be a goal of specific systems, but it does not encompass the core function that defines a closed loop control system.
