| This text to the domestic and international relevant airplane cabin pressure control system of the cultural heritage carried on a detailed reading, analyze currently at home and abroad concerning cabin pressure control system research of the progress and the present condition. Our country to cabin pressure control modulator of research start to compare with night,, still have no the system of control with numerical cabin pressure so far, and also have no a set of cabin pressure control system to imitate a true technique. So the research of this topic have aggressive meaning. This text with domestic some large conveyance machine for object, for the type's airplane design of the numerical type a few parts of the cabin pressure control system of the function carried on imitating a true research. The usage is the most advanced built-in imitated the true software StateMate MAGNUM logarithms word type airplane the function of the cabin pressure control system to carry on a research and imitate really. This text builds up the mathematics model that the row spirit of the numerical type pressure control system lives a door and the direct current electrical engineering, the usage auto control theories, deduce deliver function, and analyze the parameter of the PI control link of the system whole settle, make sure its related coefficient; The development makes use of the software of StateMate MAGNUM also, setting up the row spirit to live the door and the direct current electrical engineering to imitate true model under its environment; In the SM carried on the control result to imitate to the PI parameter for get really, and carry on excellent turn, the end gives a best system design project. According to imitate a true result, this text returns the problem to the actual possible emergence in the system to put forward some technique suggestions, controling the development target that the application of the realm put forward in the wreath to the SM software. |
