The great development of AI technology has made it possible to build up intelligent systems to resolve problems requiring qualitative and ambiguous human experience. In this paper, some new work and results are presented on the development of an intelligent CAD system for cold-forging parts in the automobile industry. The knowledge of the system is classified into three groups: facts, procedures and heuristics, then the structure of knowledge base is illustrated. To describe the geometry features of cold-forging parts, the coding of product geometry is analyzed and studied, and the coding method is shown in a figure. To predict the elastic deformation and die life, a newly developed AI technology-artificial neural network (ANN), along with fuzzy mathematics, is introduced to establish a model of fuzzy neural networks. Then learning algorithms are illuminated, and the effectiveness of this model is verified by feeding the network with test data not included in the training data.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.

Therefore, it is very important to control the idle speed stability and to keep the idle speed constant in spite of the various engine load disturbances. In order to reach this goal, usually the closed loop control is applied. Among various control algorithms, traditional PID algorithm has been used successfully for many applications. The key advantages of PID control are its simplicity and practicality. Its control parameters can be tuned on line; the flexibility of its software development makes it easier to get a better control result. In this paper, based on PID control algorithm, an idle speed control system for 462Q electronic controlled gasoline engine is developed. The hardware design of this system, the design of the digital PID controller, the selection of the sample interval and the method for tuning the control parameters are introduced in detail.","PeriodicalId":191336,"journal":{"name":"Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat.
