Abstract :
A fuzzy-logic-based command to line-of-sight (CLOS) guidance law is proposed. In this design, the guidance problem is converted to the tracking problem. Then the fuzzy controller is designed to achieve satisfactory tracking performance. Meanwhile, an on-line tuning factor is introduced to speed up the convergence of tracking error and to reduce the miss distance. Besides, a CLOS compensator is designed to eliminate the pseudo-CLOS effect. Simulation results for different engagement scenarios illustrate the validity of the proposed guidance law
