Application of Finite State Machine to Program Design of Torpedo Search Strategy

A design scheme of torpedo search strategy program based on finite state machine is presented to improve the design efficiency and readability of torpedo search strategy program, and to facilitate the modification of logic and de-bugging. The definition standard and model of homing state, event, and activity are established by analyzing the torpedo homing logic relations at such stages as searching, pursuit and identification of target. The state transition diagram of homing logic and the implementation of homing program are introduced based on the finite state machine theory. The model and design scheme are validated by simulation, and the results show that the program operation on state machine is stable; the debugging and pursuit are easy; especially, adding state, altering logic and debugging program become convenient.
