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.
