The Automotive Propulsion Control Laboratory (APCL) aims at transforming the energy storage, conversion and power transfer processes for automobiles and other mobile applications with mechatronic systems and advanced control methodologies. We investigate the replacement of mechanical components in the automotive propulsion system with electronically controlled mechatronic actuators so that significant reduction of energy consumption and emissions can be achieved. The mechatronic propulsion system and advanced control can not only improve system efficiency but also enable renewable energy for transportation. The research activities include control theory development for tracking and disturbance rejection, modeling and control of automotive propulsion systems, and design of novel actuators.
