Design of Hardware-in-the-Loop System for Large Altitude Test Facility Intake and Exhaust Control System

In order to construct a hardware-in-the-loop platform of large and complex altitude test facility intake and exhaust control system,a system design method combining simulation models and physical components is proposed.This system is divided into simulation models and physical components based on its structure and working mechanism,and its simulation models are built by theoretical modeling and system identification.Whole system and software combining simulation models and physical components are developed based on PLC.This simulation system can achieve integrated virtual simulation.The simulation results show that it runs reliably and stably and can simulate the real engine test process accurately.
