| As an important system of the aircraft, the main function of the flight control system is to be responsible for the stability and control of airplane flight attitude and track movement. Due to the requirement of modern aircraft is higher and higher, flight control system has developed into a typical involves complex systems in many areas, so its design is also becoming more and more complex. In order to implement the intelligent of the flight control system design, the knowledge engineering technology is introduced into the flight control system design process. Design the knowledge base system for flight control system, mainly for the use of the expert system of the flight control system design.(1) The digital design of flight control system is introduced and the structure of the digital design environment of flight control system is discussed. Secondly, through the overview of the structure of flight control system, and connecting with the general design process of flight control system, studied the structure of the flight control system design knowledge, divided into the knowledge of system function design, the knowledge of system layout and architecture design, model selection knowledge and some relevant auxiliary knowledge.(2) By comparing the characteristics, advantages and disadvantages of some common representation of knowledge in the field of knowledge, design the representation of knowledge in the field of flight control system design.(3) In combination with the characteristics of the knowledge of flight control system design, design a series of relation data table, mapping the knowledge to relational database to store and manage. Through the study of related reasoning mechanism, designed a preliminary reasoning mechanism of flight control system design and developed the knowledge base management system.(4) To design the flight control system redundancy ranking scheme as a verification case, testing the system running normally. |
