My academic research has been focused on the modeling and control of solenoid variable valve actuators. Such actuators are expected to play a key role in enhancing automotive combustion engine efficiency by replacing the camshaft of a traditional spark ignition engine.
As part of fulfilling my Ph.D. degree requirements, I am presently evaluating nonlinear control and position feedback techniques, both in simulation and experimentally. I am also implementing recursive gas force identification / disturbance rejection algorithms.
During the course
of my M.Sc. research, I developed a parametric finite element model (FEM)
of an electromagnetic Variable Valve Timing (VVT) actuator.
If you would like a copy of my thesis entitled "Modeling and Simulation
of Automotive Gas Exchange Valve Solenoid Actuators" please
