What is a reason for not using feedback control system?
The main reason for not using feedback control system is that time lag may cause a process deviation near the beginning of a process not to be recognized until the process output. It can result in substantial deviation throughout the entire process, causing an error to continue without adjustment. Since feedback control systems usually take input from one sensor. there may be better and more direct ways to control a system using multiple sensors. Operator intervention is usually required when the system is not able to maintain stable closed-loop control. Feedback control systems do not take predictive control actions for effects of known disturbances.
What is the definition of closed loop control system?
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
What is ferro-resonance effects?
The effects of ferro-resonance are the ungrounded primary transformers, higher distribution in the voltage systems. Other effects are the lightly loaded transformers.
What is a PID controller?
A proportional-integral-derivative controller(PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.
Are low-voltage systems totally safe Explain?
No, Their are no electrical systems that are totally safe. Elections harness electricity not control it.
Where are Effects greater than their cause?
In systems with positive feedback (or multiplier effects).

What is an open loop in control systems?
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
