英文摘要:

      The inlet/exhaust pressure control system of ATF(altitude simulated test facility) is a kernel facility which is used to simulate the flight altitude and rapidity conditions of aero-engine.The control quality of inlet/exhaust pressure control system is the main factor which decides the simulation precision of ATF.However,selection of the control parameters is an important factor affecting the dynamic characteristic of a control system.Genetic algorithm is studied and then applied to the inlet/exhaust pressure control system in order to get the optimization parameters of PID controller.According to the simulation results,genetic algorithm can get a group of optimization parameters.
