Abstract For this experiment, our laboratory group was given the task to design a controller for a control system that will satisfy a set of criteria within a certain margin. This experiment gave us the freedom to design the system as long as the following specifications were met: the percent overshoot is to be less than ten percent. The settling time is to be within two percent of the final value within a time frame of 500 milliseconds. The rise time has to be less than 200 milliseconds for unit step input. And only the tools and equipment given to us in our laboratory kits are to be used. The way our group decided to design our system was by the means of creating a digital PID controller via software by the name of LabVIEW, while the remaining parts of the circuit were constructed by using a breadboard. Along with specifications to be met, our program has to display waveform charts for both the input and output signals, the percent overshoot has to be displayed in real time along with an indicator, include a safety feature that will cease activity of the circuit when prompted, and provide the user with real time parameter controls. After fine tuning our system, our parameters for the proportional gain, Kc, integral time, Ti, and derivative time, Td, were 1.78, 0.002, and 0.00001, which provided a rise time of 0.04 seconds, settling time of 0.26 seconds, and percent overshoot of 7.87.
