Project Summary
Project 2 consisted of designing a PID controller to go along with the DC
motor model of project 1.
The controller had to be implemented so that the
overall system could meet the given specifications.
The transient and steady
state performances of the system were then analyzed to determine how the
system behaved over different time ranges.
The sensitivity of the system was
then analyzed and compared to that of project 1.
It was observed that the
system no longer met the –20db peak value.
The system was then analyzed to
observe it’s performance in rejecting disturbance over different frequency ranges.
It was found that the system rejected disturbances at high frequencies.
Finally,
the system’s noise rejecting capabilities were then analyzed over different
frequency ranges.
It was concluded that the system rejected noise, like
disturbance, at high frequencies.
All of these operations were necessary in order
to properly analyze the overall performance of the system.

Introduction
Project 1 consisted of the mathematical modeling and analyzing of a DC
motor with a load.
The mathematical model was used to create a signal flow
graph, in order for a transfer function to be derived.
The transfer function
consisted of the armature voltage as the input variable, and the angular velocity
as the output.
The transfer function was then plotted in order to analyze it’s
behavior.
In this project, project 2, we designed a PID controller to meet certain
specifications that were given.
The project required the use of the Ultimate Gain
Method as in ZieglerNichols tuning.
This method enabled us to design a PID
controller that enabled our system to meet the given specifications.
The use of
the sensitivity function, system disturbance and noise modeling were very
important parts of the project.
Matlab played a key role in providing supporting
materials through graphs and calculations.
In this project, the model of the
system with the PID controller is analyzed in detail to achieve a great
understanding of the overall system’s behavior.
