Close loop Control system ::-
It's an automatic control system in which an operation, process, or mechanism is regulated by feedback
Control Characteristics of the system depends upon the output of the system. It is also termed as feedback control system. The control action is actuated by an error signal 'e', which is the difference between Input signal and output signal. The purpose of feedback is to reduce the error between the reference input and the system output.
Advantages of Closed loop :-
i) Accurate and Reliable
ii) Reduce effect of parameter variations.
iii) Reduce the effect of non-linearity.
Disadvantages of closed loop:-
i) System is Complex & Costly.
ii) Reduce the Gain will negative feedback.
