Electrical Question: What are the Characteristics of Negative Feedback? Answer: Negative Feedback in a Control System has following Characteristics Reduction in the gain at the expense of better stability of the system Rejection of disturbance signals in the system Low Sensitivity to parameter variations Accuracy in tracking the steady state value
What are the basic components of the feedback control system? Answer: Basic components of the feedback control system are process system (open loop system), feedback path element, error detector, and controller.
Define Transfer Function? Answer: Transfer Function of a control system is defined as: i) Ratio of Laplace transform of Output to the Laplace transform of the Input with zero initial conditions
