【Abstract】 The system, which adopts barometric pressure as controlled measure, is a nonlinear and variable delay time system. To confirm such a system’s accurate mathematical model and optimum answer is very difficult. This paper proposes an intelligence hierarchical method based on the knowledge/reasoning regulation, according to the control demand. It is, guided with the knowledge base, to realize the practical scheme and operation by distributing performance parameter gradually. The system described here has outstanding stability, flexible and convenient control performance.\;更多还原
