Consideration of Genetic Algorism to Positioning Control of Electromagnetic Engine Valve

An ElectroMagnetic engine Valve (EMV) has received a great deal of attention due to the growing importance of issues such as fuel economy and environmental protection in the automotive. We study on the design of the structure of the linear actuator and the positioning controller for the EMV in order to realize the EMV. Conventionally, we realized the linear actuator and the positioning controller for the EMV. But, the mechanical and the electrical characteristics of the EMV are changing over a long time. Therefore, an adaptive controller is required in order to compensate deterioration of control performances. In this paper, we propose the positioning control using a Genetic Algorism (GA) as the first step to realize the adaptive controller. By using the GA, we realize the auto tuning method of the design parameters of the positioning controller. The effectiveness of the GA is confirmed by numerical analysis
