Engineering Technology and Management senior Cole Stephan has been awarded one of two Association of Technology, Management and Applied Engineering (ATMAE) Manufacturing Division scholarships bestowed in the nation. He will receive the scholarship on Fri., Nov. 8, at the ATMAE Annual Conference in Charlotte, N.C.

The $500 award honors Cole’s research project, “Applying Design of Experiment in Performance Optimization of an Automated Position Control System,” which focuses on an electrohydraulic system comprising an electrohydraulic cylinder with an attached controller. The proportional gain, integral gain and derivative gain affects how the cylinder responds to a certain amount of voltage within the controller. These three values demonstrate the cylinder’s position and how quickly it gets to that ideal position.

“The controller is always trying to get the cylinder in the exact position you’re telling it,” said Stephan, who worked with Associate Professor of ETM Yuqiu You and Assistant Professor of ETM Mustafa Shraim. “These values interact with how quickly it gets to that exact value and how precise it is, so changing these different values can cause different things to happen.”

According to Stephan, the project presented some challenges. In using a Raspberry Pi, a single-board computer, he had to manipulate the voltage in a way the controller could recognize it. One of Stephan’s primary struggles was turning the digital voltage into an analog signal for data collection.

Also president of OHIO’s student chapter of Epsilon Pi Tau (EPT), Stephan said he’s excited share his research poster at the ATMAE national conference.

“At the same time, I’m nervous that maybe somebody knows more than me and is going to test me, but that comes with the territory,” Stephan said. “(Epsilon Pi Tau) is also a pretty big sponsor of the event, so we’re hoping to do some networking while we’re there and explain how OHIO is utilizing EPT as well.”

You, Stephan’s mentor, has high hopes for her student.

“For this specific conference, I hope Cole can win the undergraduate research competition,” You said.
