摘　　要：针对当前基于MATLAB/SIMULINK的半物理仿真(Hardware-in-Loop Simulation,HILS)系统中不支持多领域建模、联合仿真模型转换过程复杂且存在误差等问题,提出基于Modelica和建模仿真软件MWorks进行HILS的方法,分析其所涉及的建模方法、实时仿真接口和代码生成等关键技术,并以此为基础构建支持Modelica模型的HILS.以前起落架转向系统和起落架收放系统为应用实例,建立HILS平台,对该方法进行验证.仿真结果表明该方法可行,结果可信度高.As to the issues in the Hardware-in-Loop Simulation （HILS） system based on Matlab/ SIMULINK, such as non-support of multi-domain modeling, and process complexity and error-existing during co-simulation model conversion, a HILS method is proposed on the basis of Modelica and the modeling simulation software MWorks. The key. technologies of modeling method, real-time simulation interface, code generation, and so on are analyzed and a HILS is built for Modelica model. Taking a front landing gear steering system and a landing gear retraction system as examples, a HILS platform is built and the method is verified. The simulation results show that the method is feasible, and the results are reliable.
