control system

Why is it preferable to use the feedback control system rather than open loop control system???????....what is there difference with respect to there uses...
 

Re: control system

1.Improvment of band width
2.making independet circuit parameter to paramters of elements for example β of transistor
drawback is decreasing the gain
 

control system

the variation of the parameter are more controllable in feedback system...
 

Re: control system

output is much more precise in feed-back system, and near to the desired one..
