What does the term "set point" refer to in a control system?

The term "set point" refers to the desired target value that a control system aims to maintain. This value represents the ideal condition or point at which the system is designed to operate. For example, in temperature control applications, the set point would be the specific temperature that the system is trying to achieve and maintain. The control system continuously monitors the actual value and adjusts the inputs or control actions to minimize the difference between the actual value and the set point, ensuring the system functions as intended. This concept is fundamental to control theory and is crucial for achieving stable and efficient operations in various industrial applications.
