[@asneefjaved9389]

This is the clearest explanation of fuzzy systems one can find anywhere. Thank you for this !!!

[@DrJALAGHARI]

Thanks for the compliments. Do share this video as well as channel with your friends too.

[@eduardocosta9532]

you've made a perfect and detailed presentation about replacing the 2 controllers. it was exactly what i needed. thank you.

[@DrJALAGHARI]

Thanks for the compliments.

[@HosamMostafa-h7s]

Your collection of explanations is beautiful, Dr. But can you explain how fuzzy logic controller is used to control load frequency in two power stations using MATLAB Simulink

[@DrJALAGHARI]

Thanks for the compliments. You may apply the same idea for both the two area power systems. Also, watch my other videos on this topic, they will be helpful to you.

[@irfanuetian6321]

Thank you for the wonderful presentation. It might be a good idea to further test your developed AVR on other controllers as well.

[@DrJALAGHARI]

Thanks for the compliments. You may watch my other videos, I have tested it on different controllers. You may also take the same system and apply new controller.

[@jawadulhasansaad]

First of all, thank you so much for this great presentation. It has helped me a lot. May Allah bless you.

Now, I see the limitations of FLC. But it surely has better response than PID. How about it's practical implementation ? Is it also effective and robust when taken to the hardware? As from my experience, implementation of PI-Controller actually makes some issues of delays, and can lead the system to collapse if not taken care of properly, but that's hardware limitation.

[@DrJALAGHARI]

Fuzzy logic controller has the main limitations of not being expert by itself. It totally depends upon the input, output ranges and rules provided by an expert. If there is some mistake in the rules, then it will be going to worse than even PID controller.

[@hassan_essakhi]

thank you for this tuorial,why the FLC doesn't have 2 input (error and change of error)?

[@DrJALAGHARI]

Thanks for the comment. You can add many inputs if you want. I just shown the procedure how to do it.

Sir I always enjoy your lecture,I found it difficult to understand FLC before but with your class I understand it perfectly well. I also have a problem with lookup table. Can u make a class on different types of lookup table. It will be well appreciated sir.

[@shahzaman451]

ASALAM O ALEIKUM, Respected sir your videos are very useful for me ,and helps me a lot. i have a question that the The output for PID ranges from 0 to 8 but when we designed fuzzy logic controller it decreases to 0 to 0.04, i tried to use range from 0 to 10 but the output ranges beyond the limit MY main question is that how should I defend this problem?

[@DrJALAGHARI]

Basically we are concerned with the results of fuzzy and PID. not with their ranges. therefore, it makes no difference.

[@AmitVerma-no7vj]

sir please one video on tuning of pi controller in when the plant is not lineraized

[@DrJALAGHARI]

Thanks for the comment. I will try to search for such a case and if possible try to make video on it.

[@HakanÖztürk-z6s]

If the reference input is a step function, shouldn't all rules be fixed to the same output as 1 and the fuzzy rule table be the same?

[@DrJALAGHARI]

Thanks for the comment. the fuzzy rules are used to change the output based upon input change. Therefore, there will be different values for different signals.

Thanks for the message. I think it is better to model it step by step. First model two area system and check its results. Then model three area system and check its results and so on. Otherwise it will not be possible to find the error.

[@oladipostephen8501]

Thanks so much. I have learned alot from your channel. Can you please make hybrid Fuzzy-PID for the AVR system?

[@DrJALAGHARI]

Thanks for the compliments. In Hybrid both the blocks may be used in the models. Then fuzzy logic controller may be used to tune the PID controller parameters. But in real practice, this method will not be useful due to the reason that it unnecessarily increase the complexity of the system with no ultimate advantage over the existing controllers.

[@oladipostephen8501]

@@DrJALAGHARI I quite agree with you sir. However, in some journals, some authors use metaheuristic algorithms to optimize a Fuzzy-PID controller. I guess that was just for the sake of publication.

[@DrJALAGHARI]

@@oladipostephen8501 Exactly. You are right. This is also the reason .

[@qwasrfg]

Hi. As part of my final year project work, I developed an intelligent fuzzy logic controller which was tuned using a genetic algorithm. Both the membership functions and the gains of the FLC were tuned simultaneously. The MFs and gains of both the inputs and outputs were optimised in this way. There were 2 inputs, the actual value of the control variable and its rate of change, that is, d/dt. This is similar to a PI controller, but there is an internal inference engine taking decisions.

Thanks for the comment. you may check your fuzzy rules to get better results.

[@PRATYUSHKUMAR-dz3vn]

how to choose which shape of membership function will work

[@DrJALAGHARI]

Thanks for the comment. Choosing the specific shape is challenging. It is because no any specific rule is provided. You have to choose randomly or try one by one. Usually it is better to use triangular and trapezoidal shapes for satisfactory results.
