摘　　要：参考航空发动机和重型燃气轮机的设计,将某型船用燃气轮机的进口导叶系统(IGV system)原来采用的气动控制改造为液压控制。基于Simscape工具箱,建立液压控制的船用燃气轮机IGV系统模块化仿真模型,利用该模型,借助模糊控制理论,对IGV系统中液压控制普遍使用的PID控制逻辑进行了优化。结果表明,利用Simscape工具箱搭建的新型船用IGV系统仿真模型具有一定的可行性,且优化后的控制逻辑能有效提升IGV系统的运行效果。A certain type of marine gas turbine inlet guide vane system(IGV system) adopted pneumatic control system originally is transformed into hydraulic control system by referencing the design of aviation engine and heavy duty gas turbine.A marine IGV simulation model with hydraulic control system is built based on Simscape toolbox.By using the IGV simulation model,a new control strategy based on fuzzy logic control is proposed to optimize IGV control performance.The simulation experiment shows that the IGV simulation model is feasible,and the new control strategy can improve the IGV control performance observably.
