Torpedo Thermal Propulsion System, Digital Control Study

This paper introduces the technical scheme of the HAP three-composition torpedo's heat power propulsion system, and establishes themathematical model of open circulation torpedo's heat power system, andemulate the typical situations of this system. This paper gets the stablevalues of all kinds of situations by using the mathematical model, thesevalues can be regarded as the experienced values of vague control. It is inprogress that the theory of the self adjustment vague control can beapplied in the power propulsion system. This paper designs the softwareand hardware of micro-computer control machine which can satisfy theclosed control rules of stable adjustment , different speeds in thepermanent depth and different depths in the permanent speed and finishesthe data emulation. These results show that the closed control systembased on vague control is stable ,responding speed is fast, average erroris small and the ability of resisting disturbance is strong. These resultscan satisfy the demands of the power propulsion system character in thetorpedo's tactical and technical targets and can be regarded as a kind ofthe better control program.This paper has the important reference values to developing the newhigh performance torpedo's heat power propulsion system. It can beapplied in the great technical renovation of present torpedo's powerpropulsion system. In other hand, this paper's results can be applied in thecontrol and emulation of other types of heat power systems.
