Book Description
The goal of this research project is to develop a fuel injection system which delivers the desired ratio of air/fuel mixture to small scale internal combustion engines. Small scale engines require precise fuel control, but the fuel delivery system must be small and low-power. Our research is focused on the development of a planar fuel valve with high fuel delivery rates. The planar nature allows for successful system integration with small scale engines and systems. The fuel valve is electromagnetic, as electrostatic systems are not compatible with liquid fueled systems. The valve design is designed to have a very large open to closed fluidic resistance ratio such that when the system is not being operated, that the fuel delivery rate is near zero (i.e. the valve does not leak).

Book Description
This chapter is dedicated to modeling, system identification, and control of electromagnetic actuators with the main focus on the actuators used in magnetic levitation, in fuel injection systems, and in variable valve timing (VVT). These actuators have a simple structure, good reliability, and low manufacturing costs. However, from control viewpoint, they are nonlinear systems and are open-loop unstable. Therefore, mathematical modeling, system identification-based parameter estimation, and control strategies are presented, when the moving armature is controlled around an equilibrium position or is controlled between the two extreme positions of the armature.
