Current Research Projects

  • Modeling of Charging and Discharging Processes of Lithium Ion Batteries. The goal of this project is to develop time-varying transfer function models for Lithium Ion batteries. Such models are useful for real time prediction of charge/discharge time and state of health of a battery.
  • Optimized Adaptive Control of Indoor Temperature in a Building. This goal of this project is to develop both linear and nonlinear adaptive control techniques for designing smart HVAC controllers for a building to significantly minimize its overall energy consumption, while maintaining the thermal comfort of its occupants. Such controllers are optimized to achieve a desired trade-off between cost of HVAC and comfort.
  • Real Time Control of Resistance Spot Welds. The goal of this project is to develop nonlinear adaptive control techniques for resistance spot welding processes based on simplified thermal dynamic models.
  • Predictive Learning Based Powertrain Optimization. The goal of this project is to develop algorithms for driver classification and route attributes estimation that are useful for optimizing the powertrain of a hybrid vehicle. A smart powertrain, if so equipped, is expected to optimize both fuel economy and reduce emissions along a route.
