Modeling And Simulation Of The X-type Fuel Regulator

This subject is provided by one factory of the First Group of AIPC. Analyzing completely and thoroughly the X-model fuel control system of certain missile, and modeling and stimulating the system as well as its components, this paper is aimed to make it more practicable, improve its capability, reduce the cost, and optimize its principle components and the system, in order to enable it to be remodeled in the future. Furthermore, the throttle movement speed is stimulated upon the analysis of related parameters.The hydraulic-mechanical components are the most important of the X-model fuel control system. This paper is to analyze in detail its composing, functioning and principle. Based on the flux continuum equation and power balance equation, this paper adopts the measure of linear little variable to establish the arithmetic model of its components and system. Simulink of MATLAB is used in the stimulating, changeable step integral by adopting Runge-Kutta(4,5) arithmetic. The arithmetic model and stimulating result relative to the experiment result is referred to analyze and calculate its stability and dynamic feature. To meet the practical demand, Fibonacci is adopted in optimizing the system and components to improve its stability and dynamic capability.Research indicates: the measure of linear little variable can be applied to the modeling of X-model fuel control system, and the arithmetic model established can better reflect the practicality one; components can work steadily, and with appropriate input and output, the whole system can be regarded as a closed loop of feeding-back; the stimulating result with the use of MATLAB matches the experimental one. Adopting Fibonacci in parameter-optimizing is the base for the further design and controlling, and is of great practicability in project performance.
