open Loop and closed loop system

Difference between Open-Loop Control System and Closed-Loop Control System

Control System is a system in which the behavior of the system is determined by a differential equation. It manages the devices and the systems using control loops. There are Open-Loop Control System and Closed-Loop Control System. 

Open-Loop Control System is used in applications in which no feedback and error handling are required. It is simple and economical but optimization is not possible. Maintenance of OPCS is easier.

Advantages of Open-Loop Control System:

Simple to design and implement.
Low cost and maintenance.
High speed of operation.
Can be used for systems that don’t require precise control.

Disadvantages of Open-Loop Control System:

Lack of accuracy and precision.
Susceptible to external disturbances and variations.
Not suitable for systems that require a high degree of accuracy and precision.
Closed-Loop Control System is used in applications where feedback and error handling are required. It is a complex system and not economical but optimization is possible. Maintenance of CLCS is difficult. 
Advantages of Closed-Loop Control System:
High accuracy and precision.
Robust against external disturbances and variations.
Suitable for systems that require a high degree of accuracy and precision.
Disadvantages of Closed-Loop Control System:
Complex to design and implement.
High cost and maintenance.
Slower speed of operation compared to open-loop control systems.
