    摘  要:為研究動車組客室壓力變化對旅客乘坐舒適性的影響,設計一套客室壓力控制模擬實驗系統。在分析壓力控制系統的組成和工作原理的基礎上,利用AMESim仿真軟件建立客室壓力控制系統模型,并以S函數的形式導入到Matlab/Simulink建立的模糊控制系統模型中,對AMESim和Matlab/Simulink進行聯合仿真。仿真結果表明:在所設計的客室壓力控制系統的作用下,客室內壓力和壓力變化率能夠很好地跟隨設定值變化,系統響應速度快、精度高,滿足設計要求。
    關鍵詞:客室壓力控制;模糊控制;AMESim軟件;Matlab/Simulink軟件;聯合仿真

    Abstract: In order to research the effects of pressure changes of EMU passenger compartment on human body comfort, a pressure control simulation system was designed in this paper. Based on the analyses of structure and working principle of the whole system, the passenger compartment pressure control system model was established with AMESim software, which was imported into the fuzzy control model that was already built in Matlab/Simulink platform in the form of S function. The united simulation results show the interior pressure and its changing-rate can both follow the set value well, meeting the design requirements with its high-speed and high accuracy.
    Key words: passenger compartment pressure control; fuzzy control; AMESim; Matlab/Simulink; united simulation
