Control System Design


Concerning my undergraduate final project, I am to design a controller. First things first, let me share you a little bit of what I’ve learned about the process and methods for designing a control system. This post also serves as a parameter for my progress documentation of the project.

The process of designing a control system usually makes many demands of the engineer or engineering team. These demands often emerge in step by step design procedure as follows:

  1. Study the system (plant) to be controlled and obtain initial information about the control objectives.
  2. Model the system and simplify the model, if necessary.
  3. Analyze the resulting model; determine its properties. More

means “first amongst equals”

Well, named it so mainly because this is the first post I made in 2009. Hopefully this will be the first among any other post(s) that will follow next time.

The year 2009 started with a hellish January for me. Some of you might know that I was the head of 2009 ITB power engineering excursion committe, I am eternally grateful for all of the participation given by various parties as to make this event held successfully. Thank you.

The event was fun, educative, and most of all memorable. Some of friends are to graduate next July, there’s a possibility that we wont be meeting each others for a while and maybe for a long time, so the excursion event was also purposedly intended for our last time “going out and hanging out” together as college students. Good luck guys, my prayers are with you.

January finally passed and then came along More

Oh Goodbye Dreams..


Untuk semua yang punya YM Saya, pasti sering ngeliat judul diatas sebagai status Saya.. biasanya ada tambahan juga “au revoir la France”..

Ada sebuah quote dari film the Great Debaters,

When I was a child, I talk like a child, I think like a child

But when I have grown into a man, I put all the childish things away

yah mungkin redaksinya agak berbeda, yang jadi permasalahan adalah:

Is “dreaming” considered to be a childish thing?

Baru beberapa saat yang lalu temen Saya berinisial R bilang, jangan kebanyakan mimpi, yang real aja, lo dah gede.

So, does growing up mean giving away your dreams?

Argh.. More

Hell Freezes Over.. (a story of one morning in Bandung)


Well, it is 7 o’clock in the morning.. I just got back from campus, after spending a night there doing some research. And I tell you about the journey home.. Dang! It was agonizingly cold! the temperature dropped below 20 C (I guess :P), and in equatorial country such as Indonesia, it IS considered to be cold.

How come? It is none other than because the rain was constantly pouring down all over the night, beginning at about 8pm last night, then it just steadily got heavier until when I got up at about 6am the rain was already over, leaving trails of soil scent and the cold breeze seeping through the window.

What Fela Rizki Wardana Means


What Fela Rizki Wardana Means
You are loving and compassionate.
You are able to be a foundation for other people… but you still know how to have fun.
Sometimes your emotions weigh you down, but you generally feel free from them.You are friendly, charming, and warm. You get along with almost everyone.
You work hard not to rock the boat. Your easy going attitude brings people together.
At times, you can be a little flaky and irresponsible. But for the important things, you pull it together.

You are relaxed, chill, and very likely to go with the flow.
You are light hearted and accepting. You don’t get worked up easily.
Well adjusted and incredibly happy, many people wonder what your secret to life is.

You are usually the best at everything … you strive for perfection.
You are confident, authoritative, and aggressive.
You have the classic “Type A” personality.

You are wild, crazy, and a huge rebel. You’re always up to something.
You have a ton of energy, and most people can’t handle you. You’re very intense.
You definitely are a handful, and you’re likely to get in trouble. But your kind of trouble is a lot of fun.

You tend to be pretty tightly wound. It’s easy to get you excited… which can be a good or bad thing.
You have a lot of enthusiasm, but it fades rather quickly. You don’t stick with any one thing for very long.

You are incredibly wise and perceptive. You have a lot of life experience.
You are a natural peacemaker, and you are especially good at helping others get along.
But keeping the peace in your own life is not easy. You see things very differently, and it’s hard to get you to budge.

You are a seeker of knowledge, and you have learned many things in your life.
You are also a keeper of knowledge – meaning you don’t spill secrets or spread gossip.
People sometimes think you’re snobby or aloof, but you’re just too deep in thought to pay attention to them.

You are very charming… dangerously so. You have the potential to break a lot of hearts.
You know how what you want, how to get it, and that you will get it.

You have the power to rule the world. Let’s hope you’re a benevolent dictator!

You are balanced, orderly, and organized. You like your ducks in a row.
You are powerful and competent, especially in the workplace.
People can see you as stubborn and headstrong. You definitely have a dominant personality.

You are very intuitive and wise. You understand the world better than most people.
You also have a very active imagination. You often get carried away with your thoughts.
You are prone to a little paranoia and jealousy. You sometimes go overboard in interpreting signals.

So, to all the ladies in the world, Beware!

This lion is about to ROAR!!!

Harapan dan Impian, Doa


Barusan habis ngobrol dengan teman-teman seperjuangan Air Mata Ibu Pertiwi, ya intinya mengenai rencana di masa depan gitu, tapi kita jadinya justru banyakan nyinggung masa lalu, semacem learn from the past, hehe. Kebanyakan dari kita punya masa lalu yang mirip. Contoh yang dialami oleh Saya adalah sewaktu di SMP, kelas 1 dan 2 masih tidak maksimal, santai lah pokonya, tapi untungnya kelas 3 kesadaran muncul, barulah saya terpacu untuk belajar giat agar bisa masuk ke SMA favorit. Dan di SMA favorit Saya yang katanya “gaul” ini, Saya tetap saja tidak gaul.. apa yang salah ya.. eh, maaf, hehe jadi ngelantur gini. Nah di SMA ini kelas 1 dan 2 benar-benar merupakan masa keemasan dalam kebandelan Saya, apalagi sewaktu kelas 2. Bebas dari kekangan senior yang telah lulus, dan belum dihantui oleh tanggung jawab menjalani ujian agar dapat diterima di PTN impian. Tapi untungnya, kesadaran benar-benar mencapai taraf klimaks di saat yang tepat. Tekanan dari berbagai pihak disaat kelas 3 memaksa Saya untuk benar-benar belajar dengan tekun dan sungguh-sungguh, dengan disertai doa dan tingkat ibadah yang komprehensif. Baik dari orang tua, diri sendiri, keluarga besar di kampung, maupun gebetan (ups..) semua mengharapkan masa depan Saya yang lebih baik, haha. Dan alhamdulillah sampailah Saya di kampus ini.

Merasa yang paling jago se-Indonesia, membuat Saya takabur, hilang arah dan tujuan. Serasa segala macam harapan dan impian telah tercapai, doa pun jadi kendor.. naudzubillah.. Yang pada akhirnya membuat menyesal sekarang. Berbeda dengan pada waktu sekolah dulu, kesadaran selalu datang di akhir, namun di masa kuliah ini, tidak ada yang namanya akhir kecuali kita More
