摘　　要：喷雾系统作为某高空台关键设施之一,用于模拟发动机结冰云雾环境,其喷嘴前端水压控制精度和快速稳定性对提高云雾品质和结冰试验效率具有重要意义。针对高空台喷雾供水系统组成复杂、控制回路多、控制难度大等特点,开展仿真建模和水压控制算法研究。在喷嘴元件建模方面,结合仿真阀门元件特性和试验数据,得到压力、流量和阀门开度之间的关系,并将其作为控制函数作用于节流阀上,以“受控节流阀”的方式模拟系统喷嘴的流量特性,其模拟精度可达99.96%以上。通过分析供水压力控制流程,设计前馈解耦补偿器,解决了不同喷雾耙之间的耦合问题,并通过变参数PID减弱了控制超调。最后,在AMESim/Simulink环境中对系统水压控制进行联合仿真。结果表明:喷雾耙之间的耦合性显著减弱,超调明显降低,说明该控制方法有效。The spraying system is one of the crucial facilities of one altitude test facility,which is used for simulating the icing cloud environment encountered by engines.The precision and rapid stability of water pressure control at the nozzle inlet are of paramount significance for enhancing cloud uniformity and efficiency in ice accretion tests.In response to the complexity of the altitude test facility spraying water supply system,characterized by intricate equipment composition,numerous control loops,and substantial control difficulty,research endeavors were undertaken to develop simulation models and water pressure control algorithms.The relationship between pressure,flow rate and valve opening was obtained by combining the characteristics of simulated valve components and experimental data,and it was used as a control function on the throttle valve,and the flow characteristics of the nozzle were simulated in the way of"controlled throttle valve",with the simulation accuracy of more than 99.96%.Through the analysis of the water supply pressure control process,a feedforward decoupling compensator was designed to address the coupling issues between different spraying rakes,and the control overshoot was weakened by variable parameter PID.Finally,the water pressure control system was co-simulated in AMESim/Simulink environment.The results show that the coupling between spraying rakes and overshoot are significantly weakened,which indicates that the control method is effective.
