Israel Donato-Ridgley improves upon the model predictive controller for an injection molding machine while taking in local Bavarian culture.

The Project

At the Rosenheim University of Applied Sciences in Germany, Israel Dontato-Ridgley developed a proof of concept controller that heats the cylinder of an injection molding machine as part of an industry funded project. A model predictive controller, which uses an internal plant model to determine the optimal outputs to reach the target state, was chosen to replace the previously used PID controller. The drawback of the model predictive controller is that if the model is inaccurate the performance of the controller drops significantly. Israel spent his time individually designing different approaches to mitigating the performance drops associated with model mismatch so that the controller could be deployed in real world conditions where parameters vary. He eventually achieved a 12.9% improvement under 5% mismatch before optimization, saving both production time and energy every time one of these machines is powered on and heated to operational temperatures.

Bavarian Folk Festivals

Throughout the summer Israel had many opportunities to explore Bavaria’s rich culture and history. He attended folk festivals such as Gaufest and die Sonnenwendfeier and explored places like Schloss Herrenchiemsee and Schloss Neuschawnstein. “I was awed by the jollity and the sense of community at these Bavarian festivals,” Israel says. “Everyone was more than willing to talk to me and I never felt like an outsider.” Israel noticed that his coworkers were very keen to help him in whatever way possible, whether it be with his project or with making himself at home in Rosenheim. During his free time, Israel went on bike rides, made friends and consequently improved his German by leaps and bounds.

I WAS GLAD TO HAVE A CHANCE TO EXPERIENCE AND INTEGRATE INTO ANOTHER CULTURE, AND I’M NOW SERIOUSLY CONSIDERING STUDYING, WORKING OR EVEN LIVING IN GERMANY FOR AN EXTENDED PERIOD OF TIME.

Speaking the Language

Knowing German was integral for Israel’s very positive first experience outside of the country and he is now hungry for more cultures and languages. “I was glad to have been given a chance by MISTI to experience and integrate into another culture and I’m now seriously considering studying, working or even living in Germany for an extended period of time.”
