Implementation of Fuzzy Logic Guidance Law

In this dissertation the guidance law has two variable physical variable and linguistic variable. The fuzzy rule based on both separately. The real time implementation of fuzzy logic guidance law is derived on this. Various guidance schemes are the base of guided system law. An advanced guidance law is developed against very high-speed targets. Preliminary studies have shown that the aspect angle of the interceptor at lock-on near 180 deg is a fundamental requirement for achieving small miss distance against a very high-speed target. To meet this requirement, a fuzzy guidance law in midcourse phase that is more similar to human decision making is designed. In terminal phase, aproportional and derivative-type fuzzy terminal guidance law is explored. It is shown that the integrated guidance scheme offers a near head-on homing condition before the missile enters terminal phase and provides better. nal results (smaller miss distance and wider defensible volume) than the conventional guidance law. A complete simulation study is performed to show the effects of the proposed design.
