【Abstract】 This thesis studies the control system theory and related technology of heat and vibration combined environment tester under high-linear-acceleration. The thesis is divided into 8 chapters.In chapter 1, the significance of this project on thermal-vibration combined environment tester under high-linear-acceleration is illustrated. Then the activities and unsolved problems in this kind of combined environment tester at home and abroad are introduced, and main contents of this thesis are presented finally.In chapter 2, the principle and whole structure of combined environment tester that this thesis studies are introduced, and the scheme of control system is described briefly.In chapter 3, the temperature control methods of combined environment tester are studied. The integral separation PID control, fuzzy control and fuzzy PID control are introduced respectively and related MATLAB simulations on temperature box system are compared, and final control method is decided in the end.In chapter 4, the vibrator control method of combined environment tester is studied. The principle of vibrator system is illustrated firstly, then the realization of vibrator control system and air chamber displacement feedback moving-loop rectifying system are introduced. At last vibration isolation of vibrator system is described.In chapter 5, the centrifugal control system is studied. USS communication protocol used in centrifugal control system is clarified in detail and realization of the control system is analyzed, finally flowchart of the control system is presented.In chapter 6, the control software technology is studied. Signal transmission hardware structure and software structure in the whole control system are presented firstly, and software technologies related to control system are clarified at length: serial port communication control, multi-MCU communication and interface programming between VC and MATLAB.In chapter 7, the experiment of combined environment tester is studied. Experiments on temperature control, vibrator control and combined environment have been done. The result indicates control methods adopted in the control system are valid and the combined environment tester meets technical demands specified.In chapter 8, the conclusions from the combined environment tester system are summarized and further research work is expected.更多还原
