为了研究基于燃气轮机模型的先进控制算法和故障诊断技术，需要建立准确性和实时性更好的燃气轮机实时模型。采用基于模型的设计方法，在Simulink中建立燃气轮机分段线性化实时模型，通过代码生成技术和封装技术，将模型集成在南京航空航天大学航空发动机/燃气轮机全数字仿真平台和硬件在回路平台。在硬件在回路仿真试验中，燃气轮机实时模型与非线性模型的最大相对误差不超过3%；单位步长内，实时模型在数字电子控制器中计算平均耗时为0.126 ms，最大耗时为0.131 ms，精确性和实时性均满足控制系统的要求。

In order to develop the advanced control algorithms and fault diagnosis technologies baged on the gas turbine model, it is necessary to establish a realtime model with higher accuracy and realtime performance. The modelbased design method is used to construct the gas turbine piecewise linear model with Simulink, and by using the embedded code generator and encapsulation technologies, which is then integrated with the aeroengine and gas turbine fulldigital simulation platforms and the hardwareintheloop platform at Nanjing University of Aeronautics and Astronautics. In the hardwareintheloop simulation experiment, the maximum relative error of the gas turbine realtime model and nonlinear model is less than 3%, the average time consumption of the model in the digital electronic controller is 0.126 ms, and the maximum operating time is 0.131 ms, which meet the accuracy and realtime requirements of the control system.
