Intake pressure control of high altitude platform is the key to ensure the effectiveness and reliability of high altitude simulation test. The design of intake pressure control method based on extended state observer (ESO) can effectively improve the control quality of intake pressure in high altitude platform simulation test, restrain the influence of unknown disturbance, and realize fast and stable control of intake pressure. In this paper, the development status of the intake pressure control system of high altitude platform is summarized, and the existing problems in research are pointed out. The research progress of the control technology based on ESO is systematically described. Parameter tuning methods and improved design methods of ESO are classified. The development strategy and research direction of ESO intake pressure control of high altitude platform are proposed.
