Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Modeling, System Identification, and Control of Electromagnetic Actuators by : Alexandru Forrai
Download or read book Modeling, System Identification, and Control of Electromagnetic Actuators written by Alexandru Forrai and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Microvalves are essential components of the miniaturization of the fluidic systems to control of fluid flow in a variety of applications as diverse as chemical analysis systems, micro-fuel cells, and integrated fluidic channel arrangements for electronic cooling. Using microvalves, these systems offer important advantages: they can operate using small sample volumes and provide rapid response time. This PhD dissertation presents the world first electromagnetically actuated microvalve fabricated on a single wafer with CMOS compatibility. In this dissertation, the design, fabrication, and testing results of two different types of electromagnetic microvalves are presented: the on/off microvalve and the bistable microvalve with latching mechanism. The microvalves operate with power consumption of less than 1.5 W and can control the volume flow rate of DI water, or a 50% diluted methanol solution in the range 1 - 50 æL/min. The leaking rate of the on/off microvalve is the order of 30 nL/min. The microvalve demonstrated a response time for latching of 10 ms in water and 0.2 ms in air. This work has resulted in a US patent, application no. 10/699,210. Other inventions that have been developed as a result of this research are bidirectional, and bistable-bidirectional microactuators with latching mechanism, that can be utilized for optical switch, RF relay, micro mirror, nano indenter, or nano printings.

This book was released on 2003 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In traditional internal combustion engines, a camshaft acts on the valve stems to open and close the valves. Valve timing is fixed relative to piston position. On the other hand, if a valve is flexibly controlled by a variable valve actuation (VVA) system, we can achieve significant improvements in fuel efficiency, engine performance, and emissions. One of the most advanced variable valve actuation systems is the VVA operated by an electromechanical actuator without a camshaft, the so-called bi-positional electromechanical valve drive (EMVD). Existing EMVDs characteristically use a spring to provide the required mechanical power for operating a valve. The use of a spring provides many benefits to the design of the system, but it also results in difficult design challenges. The large holding force against the spring at the ends of the stroke suggests the use of a normal-force electromagnetic actuator, which, from a servomechanical point of view, is considerably inferior to a shear-force actuator. Furthermore, the large holding force generates a large jerk at the beginning and the end of a stroke and makes it difficult to achieve soft valve landing. An innovative electromechanical valve drive (EMVD) design is proposed, which incorporates a nonlinear mechanical transformer and a shear-force actuator. This allows not only fast but also smooth valve motion, almost zero seating velocity, zero holding power, and improved control with acceptable electric power. This proposed concept is modeled, analyzed, simulated, designed, and implemented. Experimental results show the beneficial features of the promising proposed concept.
