Abstract
In order to satisfy the demand of increasingly stringent emission regulations and higher fuel economy and dynamic performance of vehicle diesel engine, the running parameters of electronic control diesel engine was controlled. The electromagnetic actuator control system is designed based on DSP56F807. The control strategy of fuzzy self-adjusted PID and establishment method of fuzzy model table for diesel engine is presented.The control experiment of fuzzy self-adjusted PID for electro-magnetic actuator and diesel engine were carred out.Experimental results prove that this control method can obtain quite a good control effect.
