In that same tradition of research excellence, our ECE faculty continues to pioneer new technical frontiers. With more than 120 of the nation's finest researchers, ECE faculty and students have published hundreds of papers during the year in top quality journals and conference proceedings.

Automatic Control

The field of Automatic Control studies how to make systems behave in a desired manner using feedback mechanisms and proper controller designs. Automatic Control plays a critical role in almost every aspect of our daily lives, including in home appliances, automobiles, aircraft, biomedical devices, manufacturing systems, the power grid, robots, and autonomous vehicles.

The Automatic Control area has a long history of major contributions to servomechanisms, manufacturing, automation, and space exploration. In this era of the Internet and information technology, faculty are addressing challenging control problems in systems with mobility and autonomy capabilities such as large robotic swarms and automated transportation systems, smart homes and cities, humanoid robots, and unmanned systems in the air, land, and sea. Tackling these complex systems requires research and education in innovative algorithms for coordination and control of large-scale systems, machine-learning techniques for perception and cognition capabilities that allow the systems to adapt to unstructured/unknown environments, and game-theoretic approaches to ensuring security and reliability. The faculty look forward to working with enthusiastic and highly motivated students to solve these challenging problems.

Computer Engineering

The biggest companies in the world—Apple, Amazon, Google, Facebook, Microsoft—are built on the technologies developed by computer engineers and computer scientists. But computer engineers are vital not only to those giant tech companies. No modern company can survive without the software and the hardware you will learn to design and to build in Computer Engineering at Purdue. As a computer engineer you will master technologies that can address critical societal needs in domains such as health care, national security, space research, technology for special needs children, and more. Computer Engineers learn about the full computing stack. They learn about hardware—from circuits to microcontrollers to general-purpose microprocessors. They learn about systems software—the operating systems, programming languages, compilers, and networking software that no modern computer can be without. They learn about algorithms that transform concepts to actions. And they learn about the grand challenges that drive modern computing: security, artificial intelligence, the Internet of Things, and beyond. Computer Engineering faculty are at the forefront of tackling these challenges through their path-breaking research which leads to high-impact inventions and which are translated to what they teach in the classrooms. Unlock your potential to shape the future of computing with Computer Engineering at Purdue.

Schweitzer Power and Energy Systems

This area focuses on electrical power engineering and the electrical to non-electrical energy conversion process. Topics of interest include electromechanical component design, power electronics design, passive component design, power magnetics, electric drives, electric propulsion systems, vehicle (ship, spacecraft, automotive) electric systems, and power system control and stability.

In the push for sustainability and reduced carbon emissions, energy conversion technologies are critical. Energy sources and systems faculty are at the forefront of modern electromechanical component and system design, analysis, and control. They also have significant efforts in power electronics – particularly in the areas of control and passive component design.

As the demand for higher reliability and efficiency on aircraft and marine platforms increases, hydraulic control systems are being replaced by electric drive systems. Research is underway to accurately model the performance of alternative power-by-wire electric drive systems. Computer simulation packages are being designed that accurately evaluate complete power-by-wire systems, including actuators, converters, electric drives, and electrical distribution systems. Evaluation and design of electric propulsion systems is also in progress. The deregulation of the electric utilities coupled with the integration of alternative energy sources provides new challenges in power distribution and control. Current research includes evaluating the impact of deregulation on power quality, optimal control of the distribution system, and instability detection.

The Schweitzer Power and Energy Area has several research and undergraduate laboratories including the Grainger Energy Conversion and Microgrid Laboratory, the Grainger Power Magnetics Fabrication Laboratory, the Energy Storage and Material Characterization Laboratory, the Electric Vehicle Systems Laboratory, the Energy Systems Simulation Laboratory, the High Speed Machines Laboratory, the Alternative Energy Grid Integration and Systems Laboratory, and the Special Projects Laboratory.
