i have a doubt, can we connect AC load instead of grid in your testcase or that LCL filter can cause inductive effect on load?
Yes, you can connect an AC load and then obtain a "voltage source" (control somewhat different). Of course, you have to maintain the DC bus voltage. For instance, you could connect the inverter to the grid tied inverter covered in the course and then you obtain a bidirectional voltage source.
Thank you 👍 great video BTW
Thank You. Great video.
Really good explanation.. Thank you so much
Thanks for the feedback!
So sad😢😢please help me
Yes, nature is crual !
Great video, I am designing a grid following inverter. for that i want to design the PLL considering 5% of 3rd harmonics at 150Hz and 5% of negative sequence. But i don't know how i can play with my PLL to make it such. I have used SRF PLL which controls the current.
Thank you for your comment and feedback. You will some Information on PLLs in later videos. Best regards.
Tricky part of PWM output filter design is the dampening required when loads are switched off/on and when load has high crest factor with pulsing high current peaks. Sets PWM filter ringing.
See Video_7_Interlocks for strategies to enable the inverter appropriately.
Hello sir , it is possible if you share me your email to ask you few questions regarding your slides ?

Hello mr , I have few questions so can you share me your emails to contact you if possible? Thanks
@ 21:38, the transfer function Iinv/Vinv={1/(L1+L2)}* 1/S. = Kp/S. But next you design PI controller where transfer changed entirely because ouput is now Vinv = C*(Iref-I). It seems confusing to me. Kindly comment.. same is true for @ 6:11
The first equation is the process (P): input Vinv,dq and output Iinv,dq. The current process output needs to be controlled. The second equation you mention is simply the controller (C): input control error Iinv,dq,SP - Iinv,dq and output Vinv,dq, i.e. a current controller. We have a standard closed-loop system. You should probably also consult video 3.
@@frankydebruyne9842 Thanks Sir! Video 3 tells everything. Your lectures are so natural and spontaneous, very normalized that anybody can understand. Really, your lectures are like art. THANKS
SUPERB!!!!!!! Even reading an entire book did not give such a crystal-clear idea....

Hi Sir, In case of Output Disturbance, How can we change the matrix [A, BC_di; 0, A_di] at 8:06
Not always easy to establish such a model. There is an example just before in the video with the inverted pendulum and Coulomb friction. In this very simple case, A_di is just zero. Hope this is helpful.
hi sir this is wonderfull please how i can mail you sir please

Hello Dr. Franky De Bruyne. Thank you very much for the good tutorials you put on your channel I enjoy watching these educational videos. Is it possible to model and control a tilt-rotor grazer (QTR UAV or TTR UAV)?
Thanks for the feedback. You will have to look at the literature. It will be a variation on the quadcopter model considered in this course. Regards.

Nice explanation enjoing this and hoping to become a PLC tech by the end of 2025, Iam preparing myself
What bibliography do you use?
Just look at video 1.
very well explained.
Sir, I have a question, in the simulink simulation from video 1:07:00 onwards, during the simulation using the "Discrete Filter" module, the expression of the filter is supposed to be in terms of z^-1 as the discretization factor, but we use z as the factor throughout the whole derivation, and the coefficients derived in the video are directly filled into the "Discrete" module, why doesn't it generate an error? Why doesn't it generate an error?
You can work with the variable z or z^-1. Just look at the slide in 09:16. I hope this is helpful.
Thanks for sharing, I have a question, at 47:40, why delat_b = 0; isn't it 1?
degree b = degree b- = 1, degree b+ = 0. I hope this is helpful.

Hello, what a great series.. thank you professor for sharing this with us. I have a question, how can I avoid the initial transient that can be observed at the start of each graph at 7:00 ? If I'm not mistaken that transient arises only because of the big difference between the reference Vdc and the real Vdc, am I correct? Is this a limitation of the IMC tuning method? Are real PV systems affected by this kind of problem or is there a solution to this? Thank you again Francesco
You are right ! You can also tune the controller more aggressively by choosing a smaller desired closed-loop time constant (= tuning parameter for IMC tuning). In some applications where the DC bus is coupled to another DC/DC inverter, it might be useful to use the DC current as a feedforward for the DC bus control. Thank you for the feedback.
it is necessary to know the real matrices A B and C ?
Yes, you need a model of the system in state-space format in order to reconstruct the state.
amazing explanation much better than paid courses thank you
Thank you sir De Bruyne, Always talking to you about "observer polynomial " and that it must be changed to have the robustness, but it is not very clear, is the purpose of this polynom is to recalibrate the model with the real process to eliminate errors of modeling, or does it have to be adjusted to change the disturbance rejection dynamics ?, can you put a video to explain the interest of this plynome? please Thanks in advance
You should have a look at part 3 ! The polynomial influences the transfer functions from N --> PV, DL --> PV, DV --> PV. You should select the observer polynomial in order to obtain the right balance between disturbance rejection (load disturbances and ouput disturbances) and sensitivity to noise. Hope this helps. No plans for a new video. Regards.
@@frankydebruyne9842Thank you very much
Many thanks. one question: if we want to connect the inverter to a 4 wire grid side, is it necessary to have a star/delta transformer with star grounded to get neutral point? can we use DC bus midpoint as neutral instead of transformer?
Or you can implement a 3ph + N grid coupling; you will need four legs !
Why is the Harris index not exactly equal to 1 for the MV controller? Looking at the final frame of the video, it seems it is estimating some nonzero impulse response coefficients even after the delay. Is this due to the ARMA estimate of the MV closed-loop being based on a finite dataset?
Exactly !
@@frankydebruyne9842 Thanks for the reply! Great series!
Thanks for the nice feedback !
Incredibly useful and informative. The only question I have is the direction of rotation of the yaw. What forces are acting on the rotors to cause it to rotate clockwise with w1 and w3 rotating clockwise? Is it not the pushing force at the outer tip of each of the propellors, acting opposite to the rotation direction- IE, wouldn’t the system rotate counter clockwise if the propeller pair was rotating at a higher speed clockwise?
Thank you for the nice feedback. The yaw rotation results from a desequilibrium in the torques. You will find the equation in the video.
Very informative and well explained. Hats off to you!!!
Thank you for the very nice feedback
The best explanation I could find. Thank you.
