摘要
传统的应急动力测试试验存在肼燃料泄露的风险,利用模型代替产品对系统进行硬件在环(Hardware-in-the-Loop,HIL)仿真测试,可以减少项目研制风险及费用,缩短产品研制周期。HIL仿真测试的有效性取决于模型对产品的仿真程度。基于各部件工作原理的数学描述,利用Matlab/Simulink对应急动力系统的模型进行研究,并利用模型实现系统的全数字仿真,结果满足要求后,将被控对象模型生成代码下载到实时仿真机进行控制器的HIL测试,模型仿真结果与HIL测试结果基本吻合。
The traditional test of aircraft emergency power system has the risk of hydrazine fuel leakage.Using the model to replace the product to carry out the system’s Hardware-in-the-Loop(HIL)test can reduce the project development risk and costs and shorten the product development cycle.The effectiveness of HIL test depends on the simulation degree of the model to product.Based on the mathematical description of the working principle of each component,the model of the emergency power system is studied with Matlab/Simulink,and the full digital simulation of the system is realized by using the mode.After the results meet the product requirements,the code generated by the controlled object model is downloaded to the real-time simulator for HIL test of the controller.The experimental data show that the model simulation results are consistent with the HIL test results.
