Fuzzy guidance law for wire-guidance torpedo under condition of incomplete information

A fuzzy guidance technique under the condition of incomplete information was proposed to solve the problem that the commonly used guidance methods can not provide very good solution for the incomplete information of targets. Based on the deeply analysis of the function on artificial-intelligence (AI) guidance and the introduction mechanism of the target information including the azimuth, distance and direction, a new technique that the weighting revision for the direction, the threshold value limit of distance and the AI transfer on the terminal guidance can use these incomplete information effectively and be applied in the combined guidance. Simulation experiments show that the AI guidance technique can use the existing incomplete information fully and make the good progress on the optimized distance and angle entering the target wake.
