What is a controller in feedback system?

A feedback controller measures the output of a process and then manipulates the input as needed to drive the process variable toward the desired setpoint. A controller reacts to setpoint changes initiated by the operators as well as random disturbances to the process variable caused by external forces.

What is meant by feedback path?

The forward path in the feedback loop is the path after the summer, that travels through the plant and towards the system output. Reverse Path. The reverse path is the path after the pick-off node, that loops back to the beginning of the system. This is also known as the "feedback path".

What is a controller in the negative feedback loop?

Controller - a device that receives inputs from the sensor and the set point. The output of the controller is termed an actuating signal. Some controllers have an internal component called a comparator that is responsible for the calculation of the error signal.

What type of control system is implemented with a feedback path?

A closed loop control system is a mechanical or electronic device that automatically regulates a system to maintain a desired state or set point without human interaction. It uses a feedback system or sensor.
