Chapter-7: Conclusion and Future Scope

7.1. Conclusion and Discussion

This research work mainly represents the modeling and simulations of some Intelligent controllers for an AGC in single power systems. In this thesis, the computer simulations results based on system non-linear differential equations have been carried out for different load changes. The differential equations have been solved by using MATLAB programming environment. In this research we basically use fuzzy logic control. We have reduced the settling time and minimized the error (∆f). We have made the settling time 4.5 second which was above 6 second in other previous records.

Our research of frequency control is suitable for universal load system. By this method, the system will be stable within 4.5 seconds which is very effective.

 7.2. Scope of Future Work

In this research, all modeling and simulation of the proposed scheme was performed by MATLAB program. These will also be performed by using the latest simulation techniques MATLAB Fuzzylogy system.

In this research, some intelligent Controllers for an AGC in single power system have successfully achieved zero steady state error, but this research has some future scopes described as follows:

a)      The research work can be further extending considering boiler dynamics.

b)      Also deferent type of intelligent controller can be tested to get the better performance.

    Nice post. I learn something new and challenging on websites I stumbleupon everyday. It’s always exciting to read content from other authors and use a little something from other sites.

  2. Elden says:

    Thanks for posting this.. It’s been a pleasure to read 🙂

  3. Dong Bering says:

    It really often times puts me at awe to think there is a blogger as strong as you in cyberspace.

  4. Kevin Litty says:

    I dugg some of you post as I cerebrated they were extremely helpful handy

  5. ghdflghkdfs says:

    This excellent website really has all the information and facts I wanted about this subject and didn’t know who to ask.

  6. how can i change my billing info (or am i being stupid, here?)

  7. Alva Sibgert says:

    I like to surf around the online world, often I will go to Digg and read and check stuff out

    I’ve said that least 3060666 times. SCK was here

  9. Thanks for your wonderful night we had a lot enjoyable !

  10. Pretty useful list of tools. Many thanks for sharing.. i never heard of some of them. Bookmarked this for potential reference if i ever need to use these apps.
    I used the twitter 1 not way too long a go and it is extremely useful!Thanks for sharing these

  11. bigcat says:

    WONDERFUL Post.thanks for share..extra wait .. …

  12. Ashraf says:

    Is it! Then you should quit your internet service as early as possible…. haha

  13. I just want to tell you that I am all new to blogs and honestly loved you’re blog. More than likely I’m want to bookmark your website . You really have remarkable writings. Regards for sharing your blog site.

    Smarty Pants…

    Brain Box…

  15. great post, was wondering if you fancy seling/renting ad space?

  16. Sleep Saver says:

    i am the fastest smartest cleverest bestest on the planet

  17. Hi, re building backlinks, has anyone tried this free scrapebox alternative? http://bestofthebeta.weebly.com/

  18. hahahahahaah report me to google for cheating the game (i sell link building methods which is black hat and against googles rules)……… i like to cheat the system to try and make money by breaking the ethical code of conduct

  19. Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at. WordPress Seo Plugin
