Thanks for the response, In PWM modulation, it is understood The issues i am facing, while i am trying to do switching in SIX STEP/Full Wave(180 Conduction Mode) modulation for my application. Can suggest some work around using this arrangement ? TIA
@@SandunKuruppu Hello, sir. I downloaded the text book. However, I couldn't solve the torque_no_test problem. I really want to keep following the video. Would you please tell me the formula number at least? Thank you.
sir what extra need to do for controlling the speed of PMSM in this simulation and I also saw people use decoupling block ,so what is the purpose of that.
Divide Va, Vb, Vc, reference signals by half the bus voltage (Vdc/2) or Vdc, depending on how you have your inverter setup. This will normalize your voltage commands to 0 to 1 or -1 to 1.
Hello Sir, I implemented this whole setup. I could see that the model works fine with speeds up to 2500rpm for speed reference. But when i increase the speed beyond that for a set id and iq value the , the feedback id and iq are not settling to the right value. Do you have any suggestion on why that might be happening ?
You can find more information on the logic here. th-cam.com/video/pM1sZEJluVk/w-d-xo.html This is listed along with my other videos. I dont have a video on Simulink implementation of it. There are different ways to achieve SVPWM. See if the above video helps. If not, I can point you to some resources.
@@SandunKuruppu Hi sir, i want to implement SVPWM algorithm to this model. I have watched all of your videos and i build a model that shown in the video. Can you give me more resources to implement SVPWM algorithm with simulink
@ Sandun Kuruppu Sir , Thank you for your videos . Can you Please make some videos on Prognostics of PMSM motors
Hopefully soon! Thank you!
Thanks Sir for such amazing videos.
Thanks and welcome!
Hi Sandun,
Amazing explanation, just one query
If in case of shunt measurement, how will it capture both cycle(High and Low) of current ?
You will have to time the sampling points based on PWM frequency.
Thanks for the response,
In PWM modulation, it is understood
The issues i am facing, while i am trying to do switching in SIX STEP/Full Wave(180 Conduction Mode) modulation for my application.

TIA
Can you add lectures on discrete control as well ? It will be helpful for the embedded implementation
That requires a lot of time. I recommend Texas Instruments Control Suite if you want to look at implementation details.
Hello,
Can you also show how to implement SVPWM logic on simulink?
Can you tell how to get speed from hall sensors?
Discrete or linear hall sensors?
Can you explain me what happen inside the block Torque_no_test ?
It is calculating the electromagnetic torque based on ABC currents.
Con you please provide the equation for Tem thats being used in the block Torque_no_test
@@Adarshh_aa Please refer to "Analysis of Electric Machines by Paul C Krause", in BLDC chapter.

@@dwarang Hello sir, did you find the formula about torque ?
sir what extra need to do for controlling the speed of PMSM in this simulation and I also saw people use decoupling block ,so what is the purpose of that.
Anmol, I have another set of lectures on my channel that explains speed control and decoupling control. Please take a look.
Sir can you upload how to add position control loop. Very helpful videos.
Yes, soon
Sir how are you doing normalization for va vb vc between 0 to 1
Divide Va, Vb, Vc, reference signals by half the bus voltage (Vdc/2) or Vdc, depending on how you have your inverter setup. This will normalize your voltage commands to 0 to 1 or -1 to 1.
Hello, how can I get this simulink model
You are expected develop your own following the video.
@sundhu kuruppo, please guide me about designing of inverter based PMSM model operated on variable frequency. Please sir
All the videos are there on my channel. Please follow them.
Sir make videos on effects of rotor position sense error on control algorithm aslo add regenerative breaking system in simulation. 🙏🙏
There should be a video on rotor position sensor error on my channel. Do you mean the theory part of it?
@@SandunKuruppu yes and and also simulation if possible

Vishnu, Can you share some of the plots that you see? What is your sampling rate? You can email to the channel email address.
@@SandunKuruppu Hello Sir,
I have shared the plots via mail. Thank you for the help.
Hello Sir,
Did u receieve the data ?
@@vishnuharikumar4135 I received Vishnu. I will get back with you once I go through with them.
Hi Vishnu, can you share the matlab model with me??,
