What kind of control is dead beat control ?

[epp]

What kind of control is it and howto apply in s and z domain?
Thanks.

deadbeat controller

A deadbeat controller is a digital controller that places all the closed loop poles in the origin. (From the analog point of view, it is placing closed loop poles at s=-inf, since z=e^Ts, ie system reaches setpoint VERY fast.) For n-zero poles, it guarantees that the system reaches the setpoint in n steps. The cost is that overshoot is usually very high, and the control signal required may be expensive to generate. As such, it is only used in extreme situations, such as weapons systems.

dead beat control

Dear all
I design inverter with dead beat control.
I have a lot of paper that hit this subject but not explain in details this control so if any one have book that explain in details this control please attach this paper in it.
Thanks

dear friend,
why there is no replay for any one.
I hope there is any one know this topic.
please any one can replay to me.
thanks.

dead-beat control

I have a lot of paper that hit this subject but not explain in details this control

As far as I have seen, digital control text books have usually a chapter on dead-beat controllers. So it's hard to believe, that you don't find an explanation. Their theory is rather simple and they can be directly designed from a z-domain model of the control process. As previously mentioned in this thread, they have some limitations.

On the other hand, they are perfect set-point controllers, if no larger variation of control process parameters must be expected.

Unfortunately, I only have some printed German books, so I can't help you in this regard.

deadbeat controler

Dear FvM,
I don't find any book that explain in details dead-beat control.
The main problem is that how can I do this control in simulation because I use this type to control in the inverter so I want to know how can I do this in simulation.
Thanks in advance.

best book for dead beat control

Hello,

I reviewed some English control theory textbooks I could access, and I must admit, that some actually don't mention deadbeat controllers, others have a brief representation, e.g. Kannan M. Moudgalya, Digital Control. That's more than nothing and may be sufficiant to implement the principle.

The textbook I was refering to is Rolf Isermann, Digitale Regelsysteme, Band1, 1987. To my opinion it's much better suited as a practical guide, particularly the detailed discussion of the DB(\[\nu\]+1) controller. It was published in English as well, and is at least available as a used book.Digital Control Systems: Amazon.co.uk: Rolf Isermann: Books I'm not aware of any electronic copies on the internet.

Best regards

Mustafa: If u have that work available with u, the modeling file using dead beat control can u please send them to me on sohaibchauhdary@gmail.com
