Hi, I followed up your steps and the model can run well. The model setting is the same with your video. However, the out waveform of Iq, Id is a very sharp jumping without a smooth transition. What's wrong with me? Could you advise?

How to Measure Ld and Lq Practicaly for BLDC Mid Drive Motor?

I came up with a trouble. why is the rs in parameters.m not visible in motor function box? Undefined function or variable 'rs'.

Great Video, but i have a question If you would controll the Current with a Speed and a position controller: how do you calculate the Parameters for them. The only thing i know is, that the Bandwidth would be smaller than that of the previous controller.

thank you very much for the explanation!!!

Thank you for a brilliant video. Didn't think of using the Back-EMF for positioning the rotor, just what I needed. But I have a question. Why not just activate phase A i.e [100]. When the rotor is locked then the rotor angle should be 0deg. or?

Can you add lectures on discrete control as well ? It will be helpful for the embedded implementation

Hi I have tried implementing the steady state PMSM as you explained . However, I am getting the a,b, c phase currents till the step time as sustained oscillations instead of the decaying oscillations you shown Can you explain to me why it happen so?

Hi Sandrum, do you mind me mentioning your work in my thesis?

Hello Sir. Great series. I'm having problems when trying to implement a different PWM method (not SVM) into FOC to control PMSMs. Can I please have your contact for some questions? Thanks alot!

Sir for attaining speed > base speed, field weakening : how can we regulate i_d current for negative values?

Hi Sundan, When watching your video ua-cam.com/video/MmP7qIxBZKs/v-deo.html I see you feed back the speed Wr and than multiply this with the torque constant. Is there any reason why you did not do this in this video? Thanks in advance!

hi sir, How I implemented Z inverse block in Simulink

hi sir, what is the name and function of the rem block. And 1/s block is the integrator block?

Hi Sir, how to measure or calculate the psir position and psir magnitude

Sensorless based

Hi Sandun, I really appreciate the time and dedication you put into this video's. I have followed all of them and I have a much better understanding of the topic, thank you for this! I was wondering could you tell me where I can find the video where you explain how to design the DC_Motor_Speed_Controller at 3:08? Thank you for your help! Mitchell

Hello Sir, I didn't find the Tem formula that you created with torque_no_test block. I have looked Introduction to Modern Analysis of Electric Machines and Drives by Paul C. Krause. Can you give more reference about it ? Thanks a lot Emin

Sir, when i try to implement this algorithm my fq and fd output is not constant (more like sine). Where should i check ? and what is your repeating sequence time values and output values ? Thanks a lot

Perfect ! Could you share us the block diagram of the simulink model or the code ? I want to change some variables and see the effects of the output

Hi sir, thank you very much for you effort, could you share us the RL values that using in your model ?

Good lecturer sir thank you🙏

Hello Prof, thank you for this fantastic lecture! I have a couple of questions though. 1. We treat the back EMF as a disturbance when designing the current controller. In physical terms, can we interpret this as since the current dynamics occur much faster than the mechanical dynamics, in the time scale where the current loop goes to its setpoint, the motor speed has barely changed (since the current/torque has to be integrated, then pass through the inertia and friction to effect a change of motor speed), so the back EMF is like a constant disturbance which the integral part of the current controller will compensate for. 2. When discussing the speed control design, we said the mechanical response is also first order, by this do you mean the behaviour of the motor speed for a input step voltage?

Hello, Can you also show how to implement SVPWM logic in Simulink?

Hello, Can you also show how to implement SVPWM logic on simulink?

Hello Sir, I have one small question regarding IPMSM drive why we have to perform autotuning process for IPMSM

Great video! I have a question. How can you keep the armature current the same in both of those two regions? We know that a transient phenomenon takes place when you jump from curve to curve. In this transient phenomenon, the current is increasing, so the torque increases, the machine accelerates, and when it accelerates, inductive voltage is increasing - so the current decreases again, and equilibrium is achieved at a higher speed. What makes us sure that the current will be the same again?

How to implement field weakening in PMDC motor?

Sorry to say but I think Electrical theta angle zero will coincide with phase a- neutral zero crossing. In your video it is different. Why?

Hello professor. Can you guide me how Tem is calculated from ia ib and ic and theta

Sir can you upload how to add position control loop. Very helpful videos.

Hi, thank you very much for video, at some point in the video you are saying that you've talked in another video about electrical vs mechanical angle for multiple pole pair machine Could point me which which video is it please? thank you in advance

Hi sir , How to reduce the block diagram in matlab , can you please send the link

Thank you for your videos. You explain things so well.

Hi, thanks for this lecture. It was useful and easy to follow. I have a question regarding the measurement of the d and q-axis inductance. You mention to lock the rotor by injecting a current in phase A and connecting phase B-C together with the negative of the source. Does this method work with delta-wound PMSMs? Again thanks for sharing your lectures!

Hi prof ! is the DC motor in this video is a SENSOR or a RESISTANT CHARGE ? or what is it please ? the reason for my question is , you have give the SPEED_ref to DC motor and not the Synchnrone one ... e ...

Hi i realy like this playlist and im learning from you the FOC simulation. however i have a question . Why do we need to REGULATE the "Id" and "Iq" ? if we can implement them directly into our "DQ_to_ABC" ? like you did "id = 2" and "iq = 0" i dont see any benefits on REGULATING. can you explain to me ? thanks in advance

Thanks a lot sir☺.

Wonderful lecture

Thanks sir for your amazing gift in making complicate things into a simple analogy, things that only genius people do.

Thank you so much sir for very useful video. Sir, how to implement this model in hardware. How to implement spwm for inverter to drive PMSM by using this model.

nice

how do you record these simulations?

Please what's the full name of the textbook?

Your VDO is good. But, How to define & calculate modulation index ?

Hi Sandun, Amazing explanation, just one query If in case of shunt measurement, how will it capture both cycle(High and Low) of current ?

Can you make a video about the clark park transformation?

Best teacher ever seen

Hello, sir. Thanks for informative lectures. I have a question. Why iq,id,i0 are used as Vqs,Vds,V0s? Is there an assumption that R is one?

Sir, we are reducing Ke using field weakening to get more speed, but is it possible to increase Ke and get more torque and lesser speeds?, as some of the applications might need more torque at lower speeds.
