Homing air-defence missile systems using a novel fuzzy-logic mode of fire control

Abstract

Problem pogađanja ciljeva u vazduhu je prilično kompleksan zadatak u kome je svaki raketni system za odbranu iz vazduha odgovoran za upravljanje paljbe. U ovom radu predstavljamo novi pristup i modus za upravljanje paljbe u sistemima odbrane protiv-vazdušne zasnovane na samonavođenjim raketama. Sredstvo za izračunavanje lansirne zone (AOZ) koristi se za tačnu procenu da li je cilj ušao u lansirnu zonu. Predloženi novi pristup u suštini koristi fazi logiku, baza znanja fazi-principima za brzinu cilja, da bi se procenila lansirna zona odmah po prvoj detekciji cilja. Naime, ona koristi pre-definisanu lansirnu zonu za različite režime letenja i različite brzine potencijalnih ciljeva, i podaci se čuvaju u tabeli traženja sa odgovarajućim prolaznim uglovima ivremenima letenja do granice lansirne zone. Komputerski modeli simulacije i eksperimenti simulacije realizuju se uz pomoć novog modela koji je napravljen u Matlab-Simulink platformi.

The problem of shooting targets in the air isa rather complex task, in which every missile system for air defence is responsible for fire control. In this paper we present a novel approach and mode for fire control in air-defence systems based on homing missiles. A device for calculation of the launching zone (AOZ) is used for intelligent estimation whether the target has entered the launching zone. The proposed novel approach makes essential use of fuzzy reasoning, a fuzzy-rule knowledge base for targets velocity, to calculate the launching zone immediately upon the first detection of a target. Namely, it uses pre-defined launching zones for different flying regimes and different velocities of potential targets, and the data are stored into a look-up table along with the associated pass angles and flying times to the launching zone border. Computational model for simulation and simulation experiments were carried out using a new model constructed in Matlab Simulink platforms.
