Abstract
The present invention relates to the generation of an integrated guidance law for aerodynamic missiles. Particularly, a Tabu search-based approach is utilized for generating an integrated fuzzy guidance law, which includes three separate fuzzy controllers. Each of these fuzzy controllers is activated in a unique region of missile interception. The method includes the following steps: establishing a missile guidance law ƒ(z), where z represents a vector containing fuzzy membership functions and guidance rules associated with the missile guidance law; and optimizing the missile launch guidance law ƒ(z) by minimizing the equation where trepresents missile interception time, r represents a distance between the missile and a target, w, wand ware weighting factors, and arepresents a missile normal acceleration, and further |r(t)|<r, where rrepresents a pre-selected allowable miss distance, and the minimization is performed by Tabu search.
