I don't know exactly why but every time I decide to write something I feel a lot better afterwards.
So I dedicate this post to my health and my head. Maybe I will be able to proceed with my research today.

A silver faded light ascend as smoothly as smoke towards the ceiling while water stays still in a pond like perfect mirror.
No sound, no words, just thoughts. Rithmically the beat of each consonant said inside my head pumps the energy into the strange form that floats around the small cell.
After a while the once smoke like light becomes a perfect ring. Like Saturn rings. I know that becouse I can feel it. I would not dare open my eyes. Not now. But I know the moment is coming.
Finaly the sunlight blessed me with warmth and I know what to do. I inhale just enough air to wisper the command. "GO!"

It is so weird when someone next to you is speaking in some language that you can not understand a single word of what is being said. So sad!
I don't want to learn a lot of different languages. But for me it feels that there are some languages that are enbued with differents souls, moods, so it is like each one of them was made to be used in different situations. For example, since i know myself as a human being I like songs that are sung in Enlgish. In the other hand, Japanese anime are a lot funnier when spoken in Japanese, the sexual tension always get higher when Spanish is used and a family meal is not a family meal without Italian words.
I wish I could master at least these ones.

Ok, I must develop a controller for a robotic arm that supress vibration of the structure and guarantees precise positioning.
First, I decided to use a Proportional controller that consist of applying a proportional gain to the input error. The error is the difference between two references. for example, if it is a position error, it will probably be the difference of the actual position of the system and the desired target position. So basically one would calculate this error, multiply by a constant value and the result would be converted into electrical singal to drive the system into the desired position.
What happens in this kind of situation, is that the electrical signal resultant from the calculation is proportional to the output speed of the actuator of the system. LOST? ok I will explain.
System = Robotic Arm
Robotic arm has motors (actuators)
Motors turn with a angular speed (mainly) proportional to the applied input voltage (electrical signal)
Better now?
Position -->Mathmatics--> Gain --> Electrical Signal --> Motor --> Speed
The thing is: Position in, speed out? Speed in time will became position but...
what if what we want is not a new position but a new speed then?
new speed --> Mathematics --> gain --> electrons --> motor --> speed
Makes more sence and the response is instantaneous. Sounds good doesn't it?
Maybe I am ready to continue my work now! Thanks for listening!
