Its the showtime!!

Alhamdulillah everything has settled and syukur the presentation has been done as what i wish for. Madam Naszariah and Sir Syazwan who access me being very nice and I manage to answer all of their question with confidence. They look very impressed and hopefully the result given will be as impressed as their face expression :p

# final report timeeeeeee

Preparing for presentation day

Since both software and hardware has been done, now is the best time to do a preparation since the presentation day is just around the corner. It is needed to have extra research and searching for some journal as a prove to support the fact in front of the accessor.

I can feel the pressure and hopefully will have the best accessor.And thanks God the accessor for this semester will not be the same lecturer as previous..hahaha

 

Search for something and end with Facebook..arghh!! hehehe

Hardware settle! pheww (+_+)

Alhamdulillah..The assembling for hardware is now fully completed. It's time for testing and obtaining the results for the desired angle and its suitable PID's value combination.

 

Function of main components for hardware:

Reset button: to reset the microcontroller

Push button: to run the circuit

L293D: act as motor driver

LM7805 voltage regulator: supply 5V for PIC

Preset: adjust the P,I,D value

Slide switch: turn ON or OFF the circuit

Potentiometer: Adjust the angle

Motor connector: connector for motor and potentiometer

 

 

Software Progress

During this week, I have met up with advisor, Mdm zaridah to get some help regarding the simulink design and theory behind the system design. From the meeting, there are some changes about the system modelling and the physical parameters for the motor.

Before this, there is a subsystem for the PID controller and since transfer function block is not needed, so the subsystem has been replaced with a PID controller block. The changes is shown in figure below:

The physical parameters use for the motor are:

R= 2.7 Ω

L= 0.004 H

Ke=0.105 Vs rad-1

Kt= 0.105 Nm A-1

J= 0.0001 Kg m2

B= 0.0000093 Nms rad

Hardware Progress

The process of etching,drilling and soldering have been completed without motor yet.

Etching & Drilling

The etching process was done manually. I had done this before during my diploma program. It is really helpful. Manual step for etching process:

1- Clean the PCB Board

2- Print the PCB layout on a piece of paper

3- Iron the printing circuit on PCB Board

4- Cut the PCB Board with required size

Use FERRIC CHLORIDE Liquid

Final step: Clean the PCB Board using Thinner liquid

50% software 60% Hardware

The designing of PCB layout has been done and will continue with the etching process by this weekend. Pheww it  is hard to minimize the number of jumper. The completed PCB layout design is shown below.

Oh before I forget, the combination of PID controller with speed and position control has been combined and the result is as shown below:

p/s: i am more worry about the software rather than hardware..oh madam help me!! (+_+)
