Modern Powertrain System Controls New

Powertrain systems have become enormously complex over the past few decades due to myriad market forces: emissions requirements, efficiency mandates, and the desire for a greater functional envelope. Once dominated by internal combustion engines, powertrain technologies now include electric machines, inverters, batteries, CVT and eCVT transmissions, and very often, in combination.

This growth in systems complexity has been accompanied and enabled by powerful digital embedded control systems. These systems may encompass hundreds of microcontrollers communicating with each other through multiple and varied serial communications busses such as CAN and Ethernet.

This course provides an overview of the design and development of these systems including hardware, software, and control theory. It discusses system-level functional and physical architectures at all levels of the powertrain system, control theory basics, system, subsystem, and component control and diagnostics design, including an overview of functional safety and cybersecurity issues. Finally, the course presents a brief review of typical powertrain controls development processes.

Piyush Desai

Piyush Desai is a hands-on technology leader with three success stories in

starting, scaling, and commercializing new technology businesses. He received an MS

and Ph.D. from the Illinois Institute of Technology, where he also served as an adjunct

faculty for teaching Motors and Drives classes.

He has over 30 years of experience with electric machine design, control

algorithm development, and simulation-driven virtual prototyping for aerospace &

defense, PV solar, and industrial applications.

Piyush held leadership roles at multiple companies and most recently was at

Turntide Technologies, a Silicon Valley startup he co-founded to commercialize high-

efficiency motors he developed during his Ph.D. work. He is now working full-time at his

consulting firm.
