A Fuzzy Approach on Guiding Model for Interception Flight

Abstract

This chapter presents an original moving control model based on the fuzzy logic, applied to some navigation special issues. The steps taken on special flight tasks prove adequacy of the fuzzy rules based model to this field. The problems of guiding on interception trajectories (applied to missiles and air fighting), of getting closer and flight coupling (applied to flight refueling or spacecrafts coupling) and of landing are candidate issues in order to be dealt with from the fuzzy perspective. The steps of this chapter are developed from a comparative study perspective involving one of the most popular techniques such as proportional navigation and the proposed fuzzy based method. Three particular forms of the proportional technique are compared against the fuzzy model. One of these particular proportional methods joins the analytic geometric relationship with the fuzzy controlled speed of the interceptor. The fuzzy fully controlled navigation in the proposed model does not impose any analytic relationship between the positions of the aircrafts. The chapter de scribes the methodology followed on fuzzy controller developing. The results emphasize performances of the fuzzy control on simulation cases and the advantages of implementing this type of automatic equipment.
