An Integrated Guidance Law Based on Fuzzy Control for Wire-guidance Torpedo

Combining the advantages of azimuth guidance method and predicted point guidance method, an integrated guidance method for wire-guidance torpedo is presented. By introducing fuzzy control, the parameters of the integrated guidance method can be adaptively adjusted according to the information of target movement and the distance between torpedo and target. Thus the torpedo can be effectively guided to the position with ideal entering distance and angle for wake homing. Simulation results show the method can guide torpedo to the target wake with required entering angle and good trajectory .
