The Research on the Rapid Development Techniques for Aero Piston Engine Interface Simulator

针对目前航空发动机接口模拟器设计中的不足,提出了一种基于DSP+MATLAB/SIMULINK的航空活塞发动机接口模拟器联合开发新方法,基于DSP设计接口模拟器硬件平台,利用SUMULINK建立发动机模型,使用RTW从发动机模型中生成可移植的嵌入式模型C代码,通过代码集成在DSP中加入发动机模型,高效快速地解决了如何在接口模拟器中融入发动机模型的难题。所设计接口模拟器能更真实准确地模拟航空活塞发动机工作状态,试验验证了接口模拟器的可靠性和该方法的可行性。

To overcome the deficiencies of the current aero engine interface simulator, a new joint development method is presented based on DSP and MATLAB/SIMULINK. The hardware platform is designed based on DSP. Modeling with MATLAB/SIMULINK,portable embedded engine model C code is generated through RTW,and the model C code is integrated into DSP. The engine model to the interface simulator is introduced quickly and effectively,therefore,the interface simulator can simulate the states of aero engine more accurately. Test showed that this new method is feasible and effective.
