摘要
针对航空发动机控制系统的半物理仿真过程中实时温度场难以模拟、接口电路的温度通道不能检验等问题,提出了一种基于模型的虚拟温度传感器设计思路。在Matlab/Simulink平台上建立传感器的变时间常数算法模型,使用RTW-EC的自动生成代码工具基于数字信号处理器(DSP)C2000微控制器设计了虚拟温度传感器,进一步结合CCS集成开发环境(IDE)对所生成的温度传感器代码进行了处理器在环(PIL)验证。仿真结果表明:所构建的虚拟传感器能够高精度模拟真实温度传感器的特性,可以满足航空发动机控制系统半物理仿真试验的要求。
Concerning the problems that during the semi-physical simulation process of aero-engine control system,real-time temperature field are difficult to simulate and temperature channel of interface circuit can＇ t be tested,a model-based design of virtual temperature sensor is proposed. Establish variable time constant algorithm model of sensor on Matlab/Simulink platform, use automatic code generation tool real-time workshop embedded coder（RTW-EC）, design virtual temperature sensor based on DSP C2000 microcontroller. Then combine code composer studio （CCS） integrated development environment （ IDE ） verify the generated temperature sensor code processor-in-loop （PIL）. Simulation results show that the proposed virtual sensor can simulate characteristics of real temperature sensor with high precision, and can meet requirements of semi-physical simulation experimental of aero-engine control system.
