I would have passed control system theory with an A if the lecturer taught like this. This man is a great engineer...and also a presenter!

I absolutely love this guy's teaching style. I wonder if he's still with Texas Instruments in 2023.

Thanks for the upload TI!

Thank you for this awesome experience. I am foreigner and always wanted to experience how in other countries they explain this things !

Like a motor control bible. Excellent work 👍

Excellent presentation! Thank you.

great vidéo Mr .

Mr. Dave , I'm totally agree with you I did graduate in physics and I´m teaching, how ac drive runs an induction motor for 25 years at YASKAWA , but I' m a mechanical technician too, and all this disciplines I use to teaching costumers, your class it's a master class thx for that , I fell like a young boy now , well done Dave

finally i understand pid's a little more. thank you

The teacher is freaking awesome

Very good explanations, thank you!

there is an interesting topic which I had reserched. I considered the switching frequency as an additional time constant within the control plant. The time constant of the motor was more than 10 times bigger than the time delay introduced by the pwm switching frequency. Normally we would neglect that pwm time delay but....I had reserched that influence of switching frequeny on the controller within FOC. I used pole-zero compensation to calculate the controller gains. I used PT1 pkant to represent that pwm tike delay. Result was that the PI controller which does not have a third zero can not compensate for that pwm time delay so there was always an overshoot or a super slow pi controller without much dynamic in the inner current loop, the Iq loop. So I used an inner PID controller et voila, extreamly fast in response to torque changes without any overshoot. I found it extreamly useful in current motor control of big high torque PMSM and at low pwm frequencies at and below of 20kHz.

Thanks very much!

13.35 I understand his feeling when I learnt control system undergrad class in 80'. The same puzzle came to mind.

Interesting didactic and really enjoyable speech!

Great Video, Thanks Guru. I understand the Ka, Kb parameter identified from R&L but how this is linked in a digital PI .

Amazing Class

Great Video, Thanks Guru. I understand the Ka, Kb parameter identified from R&L but how this is linked in a digital PI . how to get those values for a Zero cancellation digital PI.

Really great thanks so much

thank you very much, it's helps me a lot

The best video.

Could you tell me how to get in touch with the teacher?

I am from Germany and we actually have two different words for control :D Steuerung - Control with no feedback Regelung - Control with feedback

Really nice lecture

1:17:40 Question, are the peak values of the three-phase current always the same size or do these values vary with respect to each other during the control by the foe algorithm?

Thank you Sir. I am a fan your teaching... sivarajan

Thank you

Excellent video. Very very informational and definitely something I was looking for. One doubt I have over what he says is that the motor goes faster as the current increases. I am not sure about that: yes the torque should increase, but the speed should depend on the frequency in my opinion

I love these videos! Thank you for them. I'm trying to figure out how port my Simulink models into HDL code so that I can implement this on an FPGA device. Does anyone know how to do this?

Where can we get the slides?

Good afternoon! Vector control theory says that the resulting stator field vector must be kept perpendicular to the rotor magnet. If this is one magnet with two poles, then it is not difficult to imagine and understand. But in life we have a lot of magnets. For example, there can be 12 of them on a scooter motor wheel, and the rotor is located outside the stator. How to present this corner there? How is the magnetic field located?

Good presentation, A question is current loop tuning how we will set the R/L Zero , Kb gain value in digital control , how it depends on the sampling frequency .

Can I get the link of the last video of this series which focuses on implementation with registers?

Motor Control Seminar - Richard Poley & Dave Wilson, Texas Instruments: ukposts.info/slow/PLuUNUe8EVqlkaAtIzzdF7KUDvQIJ4KM_0

I bought brand new vacuum cleaner on yearly fair, under price. So i went home and figured device turns off after few seconds. Motor is ok, but control is bad, 8-pin blank chip dead ( pin 8 connected to A1 triac and i dont know marking) . Now iam watching this ! I miss my study times... Very nice video !

In 38:42 minutes you are giving your website to ınderstand mathematical background. Howeer I can reach it. Could you please share a link.

Isn't there a trick to locate the differentiator to some other point in the block diagram so that the differentiator does not put out an impulse when set point is changed

As far as phase distortions, when I studied DSP we played around with more than just the standard analog filters. Is that an approach that is used in control design? My brain always goes straight to audio whenever filters are brought up. What about high order IIR filters? Is that something that is avoided due to delay and complexity?

What happend on day 1 on the seminar

hahaha!!! lol I don't think that this could be stated more elegantly! Manager: uneducated observer!!! :D

does anybody know if P at 43:32 refers to the number of poles exactly or does he mean pole pairs?

Is the Richard video (previous presentation) available on youtube? What's the name?

anyone found the blog?

👍👍👍❤️

what kind of component were used to cotrol motor in the early 1900s or late 1800s?

Nearly every electronic problem can be solved with duct tape and a Schmitt trigger...

Somewhat frustrating. The audience participation can't be heard without a microphone. You might say there is no audio feedback from the listeners perspective. Thumbs up anyway.

Motor Control

Where is the blog now?

I recommend watching it at 1.25 speed

Sorry, but zed-transform sounds much better to me :D

5:25 How self-absorbed do you have to be to believe that you don't speak with an accent?

Which L is he talking about? My design software has four L values: Ld, Lq, L self inductance and L mutual inductance.

An American correcting English speakers on pronunciation is a bad start.
