implementing and study the PID controller in control system because of the concepts of controller are abstract and difficult to fully comprehend.
For more understanding purpose, it is advantageous to learn and apply the PID controller effectively through empirical study. Dc motor speed control using
simulation PID controller is a good application that can help students to understand the characteristic of the PID controller in control system. These equipments are a
direct application that can visualize the theoretical in real time.
1.3 Objectives
Regarding this project, there are precise objectives to be accomplished. In completing this project, objectives are the basic in selection or designing base in
order to provide a means in organizing efforts toward accomplishment those objectives.
1. To develop simulation system of PI, PD and PID controller using VB6 software.
2. To develop interfacing interacts between hardware and software. 3. To study the effect of applying PI, PD and PID controller to the Motor
System; speed. 4. To differentiate between PI, PD and PID controller through the result
obtained.
1.4 Scopes
The preparation of a detailed project scope statement is critical to project success and builds upon the major deliverables, assumptions, and constraints that are
documented during project initiation in the preliminary project scope statement. Scope will be described as the characteristics of the product, service, or result that
the project was undertaken to create. These characteristics will generally have less detail in early phases and more detail in later phases as the product characteristics are
progressively elaborated. While the form and substance of the characteristics will vary, the scope description should always provide sufficient detail to support later
project scope planning. Scopes of this project consist of:
1. Design the simulation package using the software Microsoft Visual basic 6.0 to develop the Graphical User Interface GUI to make the user become
easier to find the controller for the motor speed controller. 2. The controller in this system is PI, PD PID controller and it also shows the
output response and the characteristics of each controller output response. 3. The GUI will produce the output response for the motor system by putting
the value of motor parameter into the simulation system. 4. User will know the type of output response whether it in open loop or in
closed loop system. 5. User will know the characteristics of each output response such as settling
time Ts, rise time Tr, percent overshoot OS, Final Value, Peak time Tp, and steady state error of the system.
6. User can choose the type of controller they want to make the system more stable.
1.5 Layout of Thesis
Layout of the thesis will tell the flow of the whole thesis and its contents. This could be the referring section for this project.
Chapter 1 shows the introduction of the project, the abstract as the initial summary for whole project. Then it also contains a brief introduction that gives the
idea of the whole project. Problems that bring the idea to implement this project also stated in this chapter. This chapter also includes the main objectives of the project
and the scope of whole project. 3
Chapter 2 contains the theory of the whole project. It comprises the control system, DC motor and the parameter calculation of the motor to get the transfer
function for the motor. The transfer function consist open and closed loop transfer function. Then, the characteristic of the output response for the motor system also
include such as rise time, settling time, percent overshoot, and frequency response for the system. It also presents the theory of PID compensator that consists of
proportional controls, integral controls, derivative controls and proportional plus integral plus derivative controls. At the end it covers about Microsoft Visual Basic 6
VB6.
Chapter 3 indicates the methodology to complete and success the project. Project methodology is about defining fundamental principles, rules and manners to
complete the project. It is a way to use all available techniques, tools and approaches used to achieve predetermined objectives. It shows the flow of the project from the
beginning and illustrates with the flow chart that review the important methods that should be considered by developers before a project is carried out. It is important for
a developer to demonstrate an awareness of methodological tools available and the understanding that is suitable for the project.
Chapter 4 likewise point out the results and analysis of the project. The developed simulation system will be shown in the result part. Simulation system here
means the controller panel of the motor. For the analysis part, the system will be test and compare with MATLAB software to make sure it is in accurate condition. The
best value of Kp, Ki and Kd also will be determined and show in this part. Sample of the system also included in this part.
Chapter 5 shows the final conclusion and suggestion for future work for this project. The suggestion includes the idea how to make this simulation package more
reliable and efficient in the future. 4
