Hey Guys,
I am having a tough time in understanding the philosophy of vector control of induction motor.I have referred to atleast 10 - 15 papers on field oriented control on the internet but still at a loss in comprehending the concept in totality.
I fully understood the mathematics involved but not able to grasp the physical significance of the same & no books are offering the explanation.It is easy to state that FOC is similar to the control of DC motors but in reality it is difficult to visualise the several attributes.
Only two parameters can be changed to bring speed control in IMs
1.Input voltage
2.Input frequency
Using these how a control similar to DC motors is achieved is unclear to me!!
Can any one guide me some lucid explanation of vector control for my better understanding?..
I need to commission a drive which works on vector control next ,month & hence need clarity of the subject!!
pls help
