Which control system operates without the feedback loop?

Which control system operates without the feedback loop? Correct Answer Open Control Loop

In an automated system, the control system which operates without the feedback loop is known as Open Control Loop system. In this system, there will be no comparison made between the input and output variable.

Consider the following statements with respect to the feedback from the control systems: 1. The feedback can improve stability or be harmful to stability if it is not properly applied. 2. The feedback can always improve stability. 3. In many situations, the feedback can reduce the effect of noise and disturbance on system performance. 4. In general, the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located. Select the correct statements.
